To create a database, the user login must be one of the following principals: The server-level principal login; The Azure AD administrator for the local Azure SQL Server; A login that is a member of the dbmanager database role; Additional requirements for In a CREATE TABLE statement, CLUSTERED can be specified for only one constraint. Multicolumn key constraints are created as table constraints. The IGNORE_DUP_KEY option applies only to insert operations after the index is created or rebuilt. COLUMNSTORE_ARCHIVE will further compress the table or partition to a smaller size. Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW) Creates a schema in the current database. After it has enough pages to fill a uniform extent, another extent is allocated every time the currently allocated extents become full. Each UNIQUE constraint generates an index. Prefix local temporary table names with single number sign (#table_name), and prefix global temporary table names with a double number sign (##table_name). Create(String, Int32, FileOptions, FileSecurity) Creates or overwrites a file in the specified path, specifying a buffer size, options that describe how to create or overwrite the file, and a value that determines the access control and audit security for the file. A logical expression that returns TRUE or FALSE. If the name of a history table is specified during history table creation, you must specify the schema and table name. Use this argument with the WITH LEDGER = ON argument to create an updatable ledger table. If this clause is specified for a constraint, the constraint isn't enforced when replication agents perform insert, update, or delete operations. After you create a partitioned table, consider setting the LOCK_ESCALATION option for the table to AUTO. Performing the data consistency check is the default. FOREIGN KEY constraints can reference only columns that are PRIMARY KEY or UNIQUE constraints in the referenced table or columns referenced in a UNIQUE INDEX on the referenced table. Doing this makes sure that any CHECK constraints on partitioning columns do not have to check for null values. Note For more information, see In-Memory OLTP (In-Memory Optimization). Alias data types can't be part of the expression. Defines the columns for a user-defined table type. DEFAULT definitions can't be created on columns with a timestamp data type or columns with an IDENTITY property. The default is ASC. An error message will occur when duplicate key values are inserted into a unique index. The following example creates a user-defined table type that has three columns, one of which (Name) is the primary key and another (Price) has a nonclustered index. Arguments database_name. The default schema of the current user in the current database. This is the default setting. If schema_name is not specified, the default name resolution rules for determining the schema for the current user apply. The value of SCHEMA_ONLY indicates that the table is non-durable. For more information, see decimal and numeric (Transact-SQL). The options are as follows: Table or specified partitions aren't compressed. The following table shows the niladic functions and the values they return for the default during an INSERT statement. The search condition must evaluate to a Boolean expression and can't reference another table. For more information about the Windows and SQL collation names, see Windows Collation Name and SQL Collation Name. Table names must follow the rules for identifiers. The following example shows the use of an expression ((low + high)/2) for calculating the myavg computed column. The following parameters must be specified for data retention to be enabled. CLR user-defined types are created with the. The value ON indicates that the table is memory optimized. database_name must specify the name of an existing database. Using deterministic encryption allows searching using equality comparison, grouping, and joining tables using equality joins based on encrypted values, but can also allow unauthorized users to guess information about encrypted values by examining patterns in the encrypted column. Applies to: SQL Server 2014 (12.x) and later, and Azure SQL Database. The options are as follows: Columns using the xml data type are compressed. Use the COLUMNPROPERTY function with the AllowsNull property to investigate the nullability of any computed column in a table. Azure SQL Database Under a column that describes each job, a character string default could supply a description when an actual description isn't entered explicitly. For more information about bucket counts, see Indexes for Memory-Optimized Tables. The following example creates a table that is both a temporal table and an updatable ledger table with the explicitly named history table, the user-specified name of the ledger view, and the user-specified names of generated always columns and additional columns in the ledger view. Applies to: SQL Server 2012 (11.x) and later. Nested stored procedures can also create temporary tables with the same name as a temporary table that was created by the stored procedure that called it. See the Sequential Keys section of the CREATE INDEX page for more information. If any mutator method in the type does not return void, the CREATE TYPE statement does not execute. The following examples show how to create a temporal table linked to a new history table, and how to create a temporal table linked to an existing history table. Deterministic encryption uses a method that always generates the same encrypted value for any given plain text value. To create a login that is saved on a SQL Server database, select SQL Server authentication. Open the integrated terminal. If neither is specified, the default is (1,1). Specifies the column against which a partitioned table will be partitioned. Specifies the name of the column storing the ID of the transaction that created or deleted a row version. Using WITH ENCRYPTION prevents the view from being published as part of SQL Server replication. The login for the current connection must be associated with an existing user ID in the database specified by database_name, and that user ID must have You cannot specify a partitioning scheme on an XML index. If not specified, database_name defaults to the current database. Specifies the data type of the column, and the schema to which it belongs. CREATE TRIGGER must be the first statement in the batch and can apply to only one table. Consider the cost of enforcing FOREIGN KEY constraints when you design your database and applications. Must be supported in natively compiled stored procedures. Note. INDEX To create a procedure in Query Editor. Select Integration runtimes on the left pane, and then select +New. Specifies the name of the columns storing the sequence number of a row-level operation within the transaction on the table. The name of a case-insensitive collation. A partition function is created by using CREATE PARTITION FUNCTION. Applies to: precision Select the API template and click Create. Specifies the order in which the column or columns participating in table constraints are sorted. For more information, see updateable ledger tables and temporal tables. Specify INBOUND to copy the remote data for the table from Azure SQL Database back to SQL Server and to disable Stretch for the table. For information about the number of allowed tables, columns, constraints and indexes, see Maximum Capacity Specifications for SQL Server. If current table is partitioned, the history table is created on default file group because partitioning configuration isn't replicated automatically from the current table to the history table. In the Password box, enter a password for the new user. For a report about the amount of space allocated and used by a table, execute sp_spaceused. Encrypts the entries in sys.syscomments that contain the text of the CREATE VIEW statement. RETENTION_PERIOD = { INFINITE | number {DAY | DAYS | WEEK | WEEKS | MONTH | MONTHS | YEAR | YEARS }}. In this article. The number of UNIQUE constraints can't cause the number of indexes on the table to exceed 999 nonclustered indexes and 1 clustered index. When a table is created with DURABILITY = SCHEMA_ONLY, and READ_COMMITTED_SNAPSHOT is subsequently changed using ALTER DATABASE, data in the table will be lost. Select Add a group.. On the Choose a group type page, select Microsoft 365, and select Next.. On the Basics page, type a name for the group, and, optionally, a description. Within a database, there can be only one user-defined type registered against any specified type that has been uploaded in SQL Server from the CLR. If filegroup is specified, the table is stored in the named filegroup. Collation name can be either a Windows collation name or an SQL collation name. Identity columns are typically used with PRIMARY KEY constraints to serve as the unique row identifier for the table. On the Integration runtime setup page, select Azure, Self-Hosted, and then select Continue. If a column is nullable, and there is no explicit default value set, NULL becomes the implicit default value of the column. Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW) Creates a schema in the current database. If the table isn't partitioned and the FILESTREAM_ON clause isn't specified, the FILESTREAM filegroup that has the DEFAULT property set is used. To evaluate how changing the compression state will affect a table, an index, or a partition, use the sp_estimate_data_compression_savings stored procedure. Columns participating in a foreign key relationship must be defined with the same length and scale. In all cases, creating a nonclustered columnstore index on a table stores a second copy of the data for the columns in the index. If you don't explicitly specify nullability, the system will define the column as NULL or NOT NULL per the above requirements. The nonclustered columnstore index is stored and managed as a clustered columnstore index. Select the API template and click Create. mask_function is the name of the masking function with the appropriate parameters. When you partition a non-unique, clustered index, the Database Engine by default adds the partitioning column to the list of clustered index keys, if it is not already specified. CREATE INDEX and DROP INDEX are not supported for memory-optimized tables. Column and table indexes can be specified as part of the CREATE TABLE statement. CASCADE, SET NULL or SET DEFAULT can't be specified if a column of type timestamp is part of either the foreign key or the referenced key. Copy and paste the following example into the query window and click Execute. For code samples showing how to create memory-optimized table types, see Creating a Memory-Optimized Table and a Natively Compiled Stored Procedure. For more information, see SET QUOTED_IDENTIFIER. Session A creates a global temp table ##test in Azure SQL Database testdb1 and adds one row, Obtain global temp table name for a given object ID 1253579504 in tempdb (2), Session B connects to Azure SQL Database testdb1 and can access table ##test created by session A, Session C connects to another database in Azure SQL Database testdb2 and wants to access ##test created in testdb1. Supported constraints include PRIMARY KEY, UNIQUE, and CHECK.
