You can do it as follows - is nchar(1), is nvarchar(MAX) ![]() You need to select all persons from a list of first names, stored in field NameToSelect in table NamesToSelect, plus some additional criteria (like filtered on gender, birth date, etc) Suppose you have table Persons where person names are stored in a single field PersonName as FirstName + ' ' + LastName. The example below is a little "forced", but this can match various real cases found in legacy databases. Most of the time in such situations you have the parameter of IN clause based on some data from database. WHERE subject LIKE ALL ('%Jo%oe%','J%e')įor Sql Server you can resort to Dynamic SQL. Snowflake also supports LIKE ANY/ LIKE ALL matching:Īllows case-sensitive matching of strings based on comparison with one or more patterns. The SQL LIKE Operator The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. PostgreSQL LIKE/ILIKE ANY (ARRAY): SELECT * JOOQ could support such a synthetic predicate out of the box. The workaround is to manually expand the predicate to the equivalent SELECT * JOOQ version 3.12.0 supports that syntax:Īdd synthetic LIKE ANY and LIKE ALL operatorsĪ lot of times, SQL users would like to be able to combine LIKE and IN predicates, as in: SELECT * B) You can make the query search arguable, or sargable. This would have an upkeep cost and is not a great method. │ x LIKE ALL ('A%','%B','%C%') │ x LIKE 'A%' │ You can do this by creating a new column with a subset of the data transformed and then index it, typically during times when you would run ETL. │ THIS expression … │ IS equivalent to this expression … │ ![]() There are also and operators that represent NOT LIKE and NOT ILIKE. ![]() The operator is equivalent to LIKE, and corresponds to ILIKE. This is not in the SQL standard but is a PostgreSQL extension. I'm working with SQl Server and Oracle here but I'm interested if this is possible in any RDBMS at all.ĪNY any string in the list. The keyword ILIKE can be used instead of LIKE to make the match case insensitive according to the active locale.
