Appendix C: Data Type Details Data type conversion details Table 58 identifies each supported DataServer for MS SQL Server data type, its SQL-ODBC equivalent data type, and its supported OpenEdge equivalent data types. In the OpenEdge -equivalent data types column, the initial data type identified is the default. The data types in parentheses are alternative data types that you can specify in the schema holder for your MS SQL Server data source. Note that the SQL-ODBC data types are presented as information only; you do not need to know nor use the SQL-ODBC data types to work with the DataServer for MS SQL Server. Table 58: MS SQL Server data type details (1 of 2) MS SQL Server data type SQL-ODBC 1 data type integer SQL_INTEGER INTEGER 2 (DECIMAL) (INT64) 3 bigint SQL_BIGINT INT64 4 OpenEdge-equivalent data types smallint SQL_SMALLINT INTEGER (DECIMAL or LOGICAL) tinyint SQL_TINYINT INTEGER (DECIMAL or LOGICAL) decimal SQL_DECIMAL DECIMAL (INTEGER) (INT64) 3 numeric 5 SQL_DECIMAL DECIMAL (INTEGER) (INT64) 3 float 6 SQL_FLOAT DECIMAL (INTEGER) (INT64) 3 double precision SQL_DOUBLE DECIMAL (INTEGER) (INT64) 3 real SQL_REAL DECIMAL (INTEGER) (INT64) 3 char 7,8 SQL_CHAR CHARACTER nchar 7,8 SQL_NCHAR CHARACTER varchar 7,8 SQL_VARCHAR CHARACTER varchar(max) SQL_VARCHAR SQL_LONGVARCHAR CHARACTER CLOB 354 OpenEdge Data Management: DataServer for Microsoft SQL Server

The SQL-ODBC data types demonstrate the mapping of native MS SQL Server data types to the ODBC standard. 2. Existing or new 32-bit INTEGER data types have a maximum internal field size of 64-bits. The internal field expansion supports larger values defined as INTEGER data types. 3. Numeric expressions supported include DECIMAL, INTEGER, and INT64. 4. The OpenEdge INT64 data type enables the MS SQL Server DataServer BIGINT data type to be successfully pulled into a schema holder. 5. The DataServer truncates values in MS SQL Server decimal or numeric columns defined with a scale greater than 10. In the case of float columns, it reliably translates up to 10 places only. 6. Do not use the FLOAT or REAL data types in joins, in primary keys, or with the equality operator.
