JDBC Header Attributes
The SQL Server 2019 BDC Multitable Consumer origin generates JDBC record header attributes that provide additional information about each record, such as the original data type of a field or the source tables for the record.
You can use the record:attribute or
record:attributeOrDefault functions to access the information
in the attributes. For more information about working with record header attributes,
see Working with Header Attributes.
JDBC record header attributes include a jdbc prefix to differentiate the
JDBC attributes from other record header attributes.
The origin can provide the following JDBC header attributes:
| JDBC Header Attribute | Description |
|---|---|
| jdbc.tables | Provides a comma-separated list of source tables for the fields in the record. |
| jdbc.partition | Provides the full offset key for the partition that produced the record |
| jdbc.threadNumber | Provides the number of the thread that produced the record. |
| jdbc.<column name>.jdbcType | Provides the numeric value of the original SQL data type for each field in the record. See the Java documentation for a list of the data types that correspond to numeric values. |
| jdbc.<column name>.precision | Provides the original precision for all numeric and decimal fields. |
| jdbc.<column name>.scale | Provides the original scale for all numeric and decimal fields. |
