| Maximum number of columns per key: | 16 |
| Maximum number of columns: | 1024 |
| Maximum number of bytes in a single row when using Database Connectors for MSSQL: | 8060 |
To achieve the same sort or retrieval sequence under MSSQL as under the file system, key fields that contain signed numeric data must be preceded by a BINARY XFD directive.
Database Connectors supports the data types shown below; when it's creating tables, the following conversion rules are used, in the sequence shown:
| COBOL | SQL Server |
|---|---|
| DATE XFD directive |
DATETIME |
| BINARY XFD directive |
VARBINARY(n) (if SIZE < 255) IMAGE (if SIZE >255) |
| VAR_LENGTH XFD directive |
VARCHAR(n) (if SIZE < 255) |
| Usage FLOAT |
REAL (if SIZE = 4) |
| Usage DOUBLE |
FLOAT (if SIZE = 8) |
Any other numeric usage:
| PIC 9(n)V9(m) |
SMALLINT (if m = 0 and n < 5) INT (if m = 0 and n < 10) DECIMAL(n + m, m)(otherwise) |
Any other usage:
| PIC X(n) |
CHAR(n) (if n < 255) TEXT (if n > 255) |
