delimiter is no effect

[starbow]

hello,
agent.sources.sqlSource.delimiter.entry = ~
This delimiter is used to split the database records?
But it is no effect.The fields of the database are also separated by commas.
I try to change the source code.
private static final String DEFAULT_DELIMITER_ENTRY = "~";
Still no effect
a1.sources.s1.delimiter.entry= ~

a1.channels.c1.type = file
