Integer Codes for Data Types
In query metadata and other contexts, the defined data type for a column may be returned as an integer code. The CType (client data type) integer codes are listed in the %SQL.StatementColumnOpens in a new tab clientTypeOpens in a new tab property. For further details, refer to Select-item Metadata.
SQLType data type codes are used by ODBC and JDBC. ODBC data type codes are returned by %SQL.Statement.%Metadata.columns.GetAt() method, as shown in the example above. SQL Shell metadata also returns ODBC data type codes. The JDBC codes are the same as the ODBC codes, except in the representation of time and date data types. These ODBC and JDBC values are listed below:
