问题描述
有人可以告诉我为什么它不能编译吗?我收到缺少表达式"错误:
Can anyone tell me why this won't compile? I get a 'missing expression' error:
execute immediate 'select CASE WHEN EXISTS ( SELECT 1 from samples where samplecode = :samplecode and auditflag = 0 and ' || varFilterString || ') then 1 else 0 end from DUAL'
into varResult
using varSampleCode;
假设所有变量都正确声明.
Assume the variables are all correctly declared.
TIA
推荐答案
execute immediate 'select count(1) from DUAL
where EXISTS
( SELECT 1 from samples
where samplecode = :sample code
and auditflag = 0
and ' || varFilterString || ')'
into varResult
using varSampleCode;
