Large binary string data types (BLOB) are SQL data types that enable you to store large amounts of data, from sources such as JPG files, in binary columns.
Host Variable Formats
- OpenESQL
-
01 blob1 SQL TYPE IS BLOB(2M).
- SQL BINARY, VARBINARY and IMAGE data are represented in COBOL as PIC X (n) fields.
- OpenESQL does not perform data conversion.
- When data is fetched from the database, if the host-variable field is smaller than the amount of data fetched, the data is truncated and the SQLWARN1 field in the SQLCA data structure is set to
W. If the host-variable field is larger than the amount of data, the field is padded with null (x"00") bytes.
- Any of the following enable you to insert data into BINARY, VARBINARY or LONG-VARBINARY columns:
- Use dynamic SQL statements
- Compile your application with the ALLOWNULLCHAR directive
- Use SQL TYPE host variables
- Use
.NET Byte host variables
- OpenESQL native support is limited to handling 65000 bytes.
- OpenESQL .NET Managed Runtime
- In addition to the definitions valid for OpenESQL, the following definition is also valid for the OpenESQL .NET Managed Runtime:
01 blob2 type System.Byte[].
OpenESQL .NET Managed Runtime applications have no byte limit.
