在 代码中 需要对 用户的某个字段过滤   SQL:

SQL1:

 SELECT count(1) FROM img_chart_def d where  d.chart_name like \'%\'  and d.chart_class = \'consumeContribution\';

 

SQL2:

SELECT COUNT(1) FROM img_chart_def d where d.chart_class = \'consumeContribution\' and ( d.chart_name like \'会%\'
OR d.chart_name like \'A%\' OR d.chart_name like \'最%\' OR d.chart_name like \'品%\' OR d.chart_name like \'购%\'

or d.chart_name like \'测%\' OR d.chart_name like \'c%\' OR d.chart_name like \'注%\' OR d.chart_name like \'性%\'
OR d.chart_name like \'生%\'
OR d.chart_name like \'星%\' OR d.chart_name like \'各%\'

OR d.chart_name like \'所%\'
OR d.chart_name like \'报%\' OR d.chart_name like \'参%\' OR d.chart_name like \'服%\' or d.chart_name like \'会%\');
