Method Detail

concatenate

BitDataValue concatenate(BitDataValue leftOperand,
                       BitDataValue rightOperand,
                       BitDataValue result)
                         throws StandardException

The SQL concatenation '||' operator.

Parameters:

leftOperand - String on the left hand side of '||'

rightOperand - String on the right hand side of '||'

result - The result of a previous call to this method, null if not called yet.

Returns:

A ConcatableDataValue containing the result of the '||'

Throws:

StandardException - Thrown on error

setValue

void setValue(java.sql.Blob value)
              throws StandardException

Stuff a BitDataValue with a Blob.

Specified by:

setValue in interface DataValueDescriptor

Parameters:

value - The Blob value to set this DataValueDescriptor to

Throws:

StandardException
