![]() ![]() If is set to 1, must be specified, or the source table must have a defined primary key. If 1, the functions that are needed to query for net changes are also generated.If 0, only the support functions to query for all changes are generated.is bit with a default of 1 if the table has a primary key or the table has a unique index that has been identified by using the parameter. Indicates whether support for querying for net changes is to be enabled for this capture instance. For more information, see, sys.sp_cdc_help_change_data_capture (Transact-SQL). Whether specified or derived, is trimmed of any white space to the right of the string.Ī source table can have a maximum of two capture instances. can't exceed 100 characters and must be unique within the database. If not specified, the name is derived from the source schema name plus the source table name in the format _. The name of the capture instance used to name instance-specific change data capture objects. If the caller isn't authorized to create a role within the database, the stored procedure operation fails. The role name is trimmed of white space at the right of the string before attempting to create the role. If the role doesn't exist, an attempt is made to create a database role with the specified name. If the role currently exists, it is used. If explicitly set to NULL, no gating role is used to limit access to the change data. The name of the database role used to gate access to change data. Tables in the cdc schema can't be enabled for change data capture. Source_name must exist in the current database. is sysname, with no default, and can't be NULL. The name of the source table on which to enable change data capture. ![]() The name of the schema in which the source table belongs. Transact-SQL syntax conventions Syntax sys.sp_cdc_enable_table For a list of features that are supported by the editions of SQL Server, see Editions and supported features of SQL Server 2022. The change data capture process retrieves this information from the log and writes it to change tables that are accessed by using a set of functions.Ĭhange data capture isn't available in every edition of SQL Server. When a table is enabled for change data capture, a record of each data manipulation language (DML) operation applied to the table is written to the transaction log. Returns the configuration parameters for change data capture agent jobs.Enables change data capture for the specified source table in the current database. Returns one row for each index column associated with a change table. This table is used to map between log sequence number (LSN) commit values and the time the transaction committed. ![]() Returns one row for each transaction having rows in a change table. Returns one row for each data definition language (DDL) change made to tables that are enabled for change data capture. Returns one row for each change table in the database. Returns one row for each column tracked in a capture instance. Returns one row for each change made to a captured column in the associated source table. The articles in this section describe the system tables that store information used by change data capture operations. Applies to: SQL Server Azure SQL Database Azure SQL Managed InstanceĬhange data capture enables change tracking on tables so that data manipulation language (DML) and data definition language (DDL) changes made to the tables can be incrementally loaded into a data warehouse. ![]()
