Examples of TrimExpression

org.eclipse.persistence.jpa.jpql.parser.TrimExpression
The TRIM function trims the specified character from a string. If the character to be trimmed is not specified, it is assumed to be space (or blank). The optional trim_character is a single-character string literal or a character-valued input parameter (i.e., char or Character). If a trim specification is not provided, BOTH is assumed. The TRIM function returns the trimmed string.
JPA 1.0, 2.0:
BNF: expression ::= TRIM([[trim_specification] [trim_character] FROM] string_primary)

BNF: trim_character ::= string_literal | input_parameter
JPA 2.1:
BNF: expression ::= TRIM([[trim_specification] [trim_character] FROM] string_expression)

BNF: trim_character ::= string_literal | input_parameter

Example: UPDATE Student st SET st.sname=TRIM(st.sname)
