你好！
在使用js-sql-parser时发现一个问题:
ast = sqlParser.parse("SELECT stime, A.names, B.names FROM (SELECT stime, names FROM iaas_data.iaas_d3c0d0681cc1900) AS A LEFT JOIN (SELECT stime, names FROM iaas_data.iaas_1071f89feaa0e100) AS B ON A.stime = B.stime")

sqlParser.stringify(ast) 结果:
SELECT stime, A.names, B.names FROM (SELECT stime, names FROM iaas_data.iaas_d3c0d0681cc1900) LEFT JOIN (SELECT stime, names FROM iaas_data.iaas_1071f89feaa0e100) ON A.stime = B.stime

问题:
sqlParser.stringify(ast)后的SQL 没有 AS A 和 AS B 导致SQL错误.
