- CDS View Entity, cds_cond, INITIAL

.... lhs IS $[NOT$] INITIAL ...

Effect

Determines the initial value. This expression is true if the value of lhs is (is not) the initial value of its built-in dictionary type.

The operand lhs must stick to the context-dependent rules listed in topic CDS DDL - View Entity, cds_cond, Operands.

lhs can have any data type except for CLNT, DECFLOAT16, DECFLOAT34, DF16_DEC, DF34_DEC, DF16_RAW, DF34_RAW, LCHR, STRING, RAW, RAWSTRING, DATN, TIMN, UTCL, and GEOM_EWKB.

Notes

  • The expression IS $[NOT$] INITIAL is suitable for checking the type-dependent initial value, instead of comparing it with a type-compliant operand that contains the initial value.
  • The expression IS $[NOT$] INITIAL must not be confused with the expression IS $[NOT$] NULL.

Example

The following CDS view entity reads all rows from the DDIC database table DEMO_DDIC_TYPES in which the column INT8 does not contain its initial value 0.
