To Reproduce

function getParser() {
  if (!parser) {
    // 👇 动态 require，仅在首次使用时初始化
    const NodeSQLParser = require('node-sql-parser')
    parser = new NodeSQLParser.Parser()
  }
  return parser
}

  const testSql = `create external table test20260108 (
    name string,
    salary float
  )
  comment '建表示例'
  partitioned by (
    prov_id string,
    date_id string
  )
  row format serde
    'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
  with serdeproperties (
    'field.delim'='#',
    'serialization.format'='#',
    'serialization.encoding'='UTF-8'
  )`;

  try {
    const ast = new getParser().parse(testSql, { database: 'hive' });
    console.log('node-sql-parser success！AST:', ast);
  } catch (e) {
    console.error('fail:', e.message, e.stack);
  }

node-sql-parser version: 5.3.13
node version: 16.20.2

Expected behavior
Support for "create external table" statements.
Support for "partitioned" statements.
