Syntax for strings in ij commands

Syntax

'Text'

Description

Some ij commands require strings. ij strings are represented by the same literal format as SQL strings and are delimited by single quotation marks. To include a single quotation mark in a string, you must use two single quotation marks, as shown in the examples below. ij places no limitation on the lengths of strings, and will treat embedded new lines in the string as characters in the string.

Some ij commands execute SQL commands specified as strings. Therefore, you must double any single quotation marks within such strings, as shown in the second example below.

The cases of letters within a string are preserved.

Example

This is a string in ij     And this is its value
'Mary''s umbrella'          Mary's umbrella
'hello world'               hello world

--returns Joe's
execute 'VALUES ''Joe''''s''';
