IIF
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The IIF() function checks if the first argument is TRUE to produce the second argument, or the third argument otherwise. It works in a similar way as the NVL2 function or the CASE expression
SELECT iif(1 = 1, 3, 4), iif(1 = 2, 3, 4);
create.select( iif(inline(1).eq(inline(1)), inline(3), inline(4)) iif(inline(1).eq(inline(2)), inline(3), inline(4))).fetch();
The result being
+-----+-----+ | iif | iif | +-----+-----+ | 3 | 4 | +-----+-----+
Dialect support
This example using jOOQ:
iif(inline(1).eq(inline(2)), inline(3), inline(4))
Translates to the following dialect specific expressions:
-- ACCESS, SQLSERVER iif(1 = 2, 3, 4) -- ASE, AURORA_POSTGRES, BIGQUERY, COCKROACHDB, DB2, DERBY, DUCKDB, EXASOL, FIREBIRD, H2, HANA, HSQLDB, INFORMIX, ORACLE, -- POSTGRES, REDSHIFT, SNOWFLAKE, SQLDATAWAREHOUSE, SQLITE, SYBASE, TERADATA, TRINO, VERTICA, YUGABYTEDB CASE WHEN 1 = 2 THEN 3 ELSE 4 END -- AURORA_MYSQL, MARIADB, MEMSQL, MYSQL if(1 = 2, 3, 4)
(These are currently generated with jOOQ 3.19, see #10141), or translate your own on our website
