MBDT and DBMS Data Types

The DSNTEP2 and DSNUTILB batch utilities use ODBC, and therefore ODBC data types, to communicate with a DBMS. The following table shows the supported DBMS data types these utilities support. Footnotes provide additional information and/or restrictions.

1 Supported in DSNTEP2 and DSNUTILB (LOAD and UNLOAD) with cited equivalent data types

  • For PostgreSQL data type BYTEA, the sqlvar.sqllen is 255
  • For Oracle data type RAW, the maximum width is 200
  • For SQL Server data type TINYINT, OpenESQL maps it to SMALLINT
  • For SQL Server data type BIT, OpenESQL maps it to TINY (one byte)
  • For SQL Server data type GUID, OpenESQL maps it to CHAR (36)
  • For PostgreSQL data type BOOLEAN, OpenESQL maps it to VARCHAR(5)

2 PostgreSQL data types DECIMAL and NUMERIC are supported in DSNTEP2 and DSNUTILB (LOAD and UNLOAD) where the supported range is s <= p <= 38.

3 Oracle DATE data type has both date and time, and is supported in DSNTEP2 and DSNUTILB (LOAD and UNLOAD)

4 Supported in DSNTEP2 but unsupported in DSNUTILB (LOAD and UNLOAD)

5 Unsupported in DSNTEP2 and DSNUTILB (LOAD and UNLOAD)
