SELECT ' OR PersonName like ''' + + '%'''ĮXECUTE sp_executesql can do this dynamically for a large number of elements, at the expense of performance, but it works. it will actually generate where clause PersonName Like 'param1%' or PersonName Like 'param2%' or. prepare the where sub-clause to cover LIKE IN (.) 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) The equals operator treats wild-card characters as literal characters. Suppose you have table Persons where person names are stored in a single field PersonName as FirstName + ' ' + LastName. LIKE is generally used only with strings and equals (I believe) is faster. 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. The 'OR' operator applies to expressions. 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. PostgreSQL LIKE/ILIKE ANY (ARRAY): SELECT * JOOQ could support such a synthetic predicate out of the box. Their syntax is identical, but LIKE is case-sensitive, while ILIKE is case-insensitive. ![]() The workaround is to manually expand the predicate to the equivalent SELECT * LIKE and ILIKE allow pattern matching within character-based column data. 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 * Becoming proficient in using the LIKE operator will allow you to parse through large databases with ease, and retrieve exactly the data you need. │ THIS expression … │ IS equivalent to this expression … │ To perform a case-insensitive pattern match for multibyte characters, use the LOWER function on expression and pattern with a LIKE condition. ILIKE performs a case-insensitive pattern match for single-byte UTF-8 (ASCII) characters. 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. LIKE performs a case-sensitive pattern match.
