新增
aggregateFunctions
参数(CountSqlParser
), 允许手动添加聚合函数(影响行数),所有以聚合函数开头的函数,在进行 count 转换时,会套一层。其他函数和列会被替换为 count(0),其中count列可以自己配置。
增加 aggregateFunctions
参数后,和原先最大的区别是,如果存在 select ifnull(xxx, yy) from table ...
,原先的 count 查询是 select count(0) from (select ifnull(xxx, yy) from table ...) temp_count
,现在会区别聚合函数,如果不是聚合函数,就会变成 select count(0) from table ...
。
默认包含的聚合函数前缀如下:
"APPROX_COUNT_DISTINCT," + "ARRAY_AGG," + "AVG," + "BIT_" + //"BIT_AND," + //"BIT_OR," + //"BIT_XOR," + "BOOL_," + //"BOOL_AND," + //"BOOL_OR," + "CHECKSUM_AGG," + "COLLECT," + "CORR," + //"CORR_," + //"CORRELATION," + "COUNT," + //"COUNT_BIG," + "COVAR," + //"COVAR_POP," + //"COVAR_SAMP," + //"COVARIANCE," + //"COVARIANCE_SAMP," + "CUME_DIST," + "DENSE_RANK," + "EVERY," + "FIRST," + "GROUP," + //"GROUP_CONCAT," + //"GROUP_ID," + //"GROUPING," + //"GROUPING," + //"GROUPING_ID," + "JSON_," + //"JSON_AGG," + //"JSON_ARRAYAGG," + //"JSON_OBJECT_AGG," + //"JSON_OBJECTAGG," + //"JSONB_AGG," + //"JSONB_OBJECT_AGG," + "LAST," + "LISTAGG," + "MAX," + "MEDIAN," + "MIN," + "PERCENT_," + //"PERCENT_RANK," + //"PERCENTILE_CONT," + //"PERCENTILE_DISC," + "RANK," + "REGR_," + "SELECTIVITY," + "STATS_," + //"STATS_BINOMIAL_TEST," + //"STATS_CROSSTAB," + //"STATS_F_TEST," + //"STATS_KS_TEST," + //"STATS_MODE," + //"STATS_MW_TEST," + //"STATS_ONE_WAY_ANOVA," + //"STATS_T_TEST_*," + //"STATS_WSR_TEST," + "STD," + //"STDDEV," + //"STDDEV_POP," + //"STDDEV_SAMP," + //"STDDEV_SAMP," + //"STDEV," + //"STDEVP," + "STRING_AGG," + "SUM," + "SYS_OP_ZONE_ID," + "SYS_XMLAGG," + "VAR," + //"VAR_POP," + //"VAR_SAMP," + //"VARIANCE," + //"VARIANCE_SAMP," + //"VARP," + "XMLAGG"
想要增加新的聚合函数前缀可以配置 aggregateFunctions,多个值用英文逗号隔开。
