Using variable subscripts in SQL
Use of subscript operations on host variables in static SQL statements is not supported by Genero BDL.
IBM® Informix® 4GL allows to use subscripts operators on host variables in static SQL statements. For example:
DEFINE var VARCHAR(40)
SELECT * FROM tab WHERE col = var[2,3]
When doing this, I4GL will silently ignore the [2,3]
operator, to use the full
variable value!
Unlike I4GL, the Genero BDL compiler denies this syntax, and is considered as bad practice.
