MySQL error code ‘1064’ troubleshooting process

Afternoon self-test code, stuck on this update for an hour and a half, greatly reduced the development productivity, send out the screening process, good soldiers will not fall into the same trap. First, type out the exception stack.

and my Ibatis SQL

<update id="updateById"  parameterClass="Org">
		UPDATE org
		SET	name = #name:VARCHAR#,
			<isNotNull property="tree_level">tree_level = #tree_level#, </isNotNull>
			<isNotNull property="yn">yn = #yn#, </isNotNull>
			<isNotNull property="route">route = #route:VARCHAR#, </isNotNull>
			`version` = `version` + 1,
			<isNotNull property="editor">editor = #editor:VARCHAR#  </isNotNull>
			
		WHERE id = #id#
	</update>

like this stack does not clearly indicate the cause of SQL problems, troubleshooting problems must be according to the error code to check. Baidu checked the 1064 error code. The column name of the table overlaps with the Mysql keyword. OK, I took this SQL close to the mysql client query interface and found that the name field changed to the color of the keyword. I thought I found the problem, so I put back quotes around the name. Run the unit test again and report an error of 1064.

There is no way out, only ibATIS executed SQL typing out, put into mysql client to see. OK, log4J plus log, the execution of IBATIS SQL typing out. Run the unit test again and the SQL doesn’t come out.
There is a feeling of frustration that should not be called indolent every day!
You have no choice but to look at SQL with your eyes. If the Editor field is null, then there are extra commas before the WHERE. Adjust the SQL.

	<update id="updateById"  parameterClass="Org">
		UPDATE org
		SET id = #id# ,
			<isNotNull property="name">`name` = #name:VARCHAR#, </isNotNull>
			<isNotNull property="tree_level">tree_level = #tree_level#, </isNotNull>
			<isNotNull property="yn">yn = #yn#, </isNotNull>
			<isNotNull property="route">route = #route:VARCHAR#, </isNotNull>
			<isNotNull property="editor">editor = #editor:VARCHAR# , </isNotNull>
			`version` = `version` + 1
		WHERE id = #id#
	</update>

Then run the unit test and the SQL executes successfully. Just log can not type out SQL, this time to type out. Where have you been when I need you?Mysql’s error code is not reliable at all! The SQL syntax is obviously wrong, but the code of 1064 is quoted.

Remove the back quotes from the Name and Version fields and the SQL will still execute normally. Fun!
