Re: Flink 1.11里如何parse出未解析的执行计划

[silence]

我简单写了一下仅供参考

import org.apache.calcite.config.Lex;
import org.apache.calcite.sql.SqlNode;
import org.apache.calcite.sql.SqlNodeList;
import org.apache.calcite.sql.parser.SqlParseException;
import org.apache.calcite.sql.parser.SqlParser;
import org.apache.flink.sql.parser.impl.FlinkSqlParserImpl;
import org.apache.flink.sql.parser.validate.FlinkSqlConformance;

/**

public class Test {
    public static void main(String[] args) throws SqlParseException {
        String sql = "xxx";
        SqlParser.Config sqlParserConfig = SqlParser
                .configBuilder()
                .setParserFactory(FlinkSqlParserImpl.FACTORY)
                .setConformance(FlinkSqlConformance.DEFAULT)
                .setLex(Lex.JAVA)
                .setIdentifierMaxLength(256)
                .build();
        SqlParser sqlParser = SqlParser.create(sql, sqlParserConfig);
        SqlNodeList sqlNodes = sqlParser.parseStmtList();
        for (SqlNode sqlNode : sqlNodes) {
            //do something
        }
    }
}
