Conditions for the Strict Mode

The strict mode of the syntax check in Release 7.40, SP05 applies to all Open SQL statements that use one of the following attributes introduced in Release 7.40 SP05:

Listings of operands as comma-separated lists

Escape character @ in front of host variables

SQL expressions

Addition USING CLIENT

Joins:

ON conditions without a column from a database table or view specified on the right side as an operand.

Multiple consecutive joins where a join expression (and not a database table or view) is on the right side of a join expression.

Use of RIGHT OUTER JOIN

Fields from the right side specified in LEFT OUTER JOIN or from the left side in RIGHT OUTER JOIN in the WHERE condition.

Access to CDS entities using SELECT.

Rules for the Strict Mode

The strict mode of the syntax in Release 7.40, SP05 checks whether the following additional rules are followed:

Any errors that would normally be displayed as syntax warnings are reported as syntax errors.

All lists of operands must be comma-separated lists. This affects the following:

In the statement SELECT, columns, aggregate expressions, or SQL expressions specified in the SELECT list and columns specified after GROUP BY and ORDER BY.

In the statement UPDATE, change expressions specified after SET.

Host variables must be prefixed with the escape character @.

If an explicit comma-separated list is specified without the addition DISTINCT in the SELECT list, all columns of the results set defined here must exist as identically named components in a structure or table specified after INTO CORRESPONDING FIELDS.

Addition CLIENT SPECIFIED can only be used for client-specific data sources.

If the addition FOR ALL ENTRIES is used, no database fields of the predefined types STRING and RAWSTRING plus LCHR and LRAW can occur in the SELECT list.

*dbtab cannot be specified for the data source in the obsolete short forms.

Comma-separated lists of operands and the escape character @ can only be used in programs in which the program attribute fixed point arithmetic is activated.
