Table name processing failed :

Error message

Table name processing failed : 

What it means

Identical to the 4.9-module error but in mybatis-plus-jsqlparser-5.0: DynamicTableNameJsqlParserInnerInterceptor failed to rewrite table names, the fallback to super.processTableName(sql) also failed (or was disabled), and ignoreException is false, so the original exception is rethrown wrapped in MybatisPlusException. The 5.0 module bundles jsqlparser 5.x, which parses newer SQL syntax.

Solutions

1. Unwrap the cause to tell a parser limitation apart from a TableNameHandler bug; fix the handler if it is user code.
2. Verify one single jsqlparser version (5.x) is on the classpath and matches the support module (mvn dependency:tree | grep jsqlparser).
3. Set ignoreException=true so un-parseable statements pass through unchanged when dynamic renaming is best-effort.
4. Simplify or split the failing statement if it relies on syntax outside jsqlparser's grammar.

Example fix

// before
DynamicTableNameJsqlParserInnerInterceptor p = new DynamicTableNameJsqlParserInnerInterceptor();
// strict: failure aborts SQL

// after
DynamicTableNameJsqlParserInnerInterceptor p = new DynamicTableNameJsqlParserInnerInterceptor();
p.setIgnoreException(true);

// Classpath guard: exactly one jsqlparser (5.x) version alongside the 5.0 support module
// mvn dependency:tree -Dincludes=com.github.jsqlparser:jsqlparser  -> single 5.x entry expected

try {
    mapper.selectList(wrapper);
} catch (MybatisPlusException e) {
    if (String.valueOf(e.getMessage()).contains("Table name processing failed")) {
        log.error("dynamic table rewrite failed; cause:", e.getCause() != null ? e.getCause() : e);
    }
}

When it happens

Trigger: Running with the jsqlparser-5.0 support module and executing SQL that even jsqlparser 5.x cannot parse, or a TableNameHandler that throws; with shouldFallback controlling whether the parent implementation is retried and ignoreException=false by default.

Common situations: Mixing the 5.0 support module with an older jsqlparser jar actually resolved on the classpath (version conflict); exotic vendor syntax beyond even jsqlparser 5.x; handler bugs on sharded/dynamic table names.
