This article is about how MyBatis dynamically passes in table names and field name parameters. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
To dynamically pass table and column names, you need to make the following modifications:
Add property statementType= "STATEMENT"
At the same time, the values of owned variables in sql are changed to ${xxxx} instead of # {xxx}.
Delete from ${table} where
${col}
< ${date}]]>1. Any one of statementType:STATEMENT (non-precompiled), PREPARED (precompiled) or CALLABLE, which tells MyBatis to use Statement,PreparedStatement or CallableStatement, respectively. Default: PREPARED. It is clear that precompilation cannot be used here, but should be changed to non-precompiled.
2. ${xxxx}: $displays the incoming data directly and generates it in sql. For string data, you need to put quotation marks manually.
String dateStr = DateFormatUtils.format (date.getTime (), "yyyy-MM-dd HH:mm:ss")
DateStr = "'" + dateStr + "'"
