Open SQL - Release-Dependent Syntax Check Modes

In Release 7.40, SP02, a new SQL parser for Open SQL was introduced, used for both statically specified Open SQL statements and for dynamic tokens, and which applies some rules more strictly than the previous parser. In Release 7.40, SP02, the new parser was used only for the statement SELECT and, from Release 7.40, SP05, for all Open SQL statements. The corresponding syntax revisions can be found under the release-dependent changes for 7.40 SP02 and 7.40 SP05.

Alongside these general revisions (which apply to all Open SQL statements), Release 7.40, SP05 also introduced syntax check modes known as strict modes, which check Open SQL statements even more strictly if they use attributes introduced in the release in question.

Other versions: 7.31 | 7.40 | 7.54


  • The release-dependent strict modes are generally downward compatible, since they are applied only if an attribute is used that was not present in previous releases.

  • The strict modes in later releases contain the rules from all preceding releases. More specifically, all strict modes demand Unicode programs in which the program attribute fixed point arithmetic is activated.
