谁能告诉我红色那段sql代表的含义，我怎样才能要他语法通过

${if(len(key) == 0,"","AND pl.pickkey in (" + key + ")")}
你sql语句模板还没替换完
什么叫模板没替换完？我问的是${if()}和红色里面的sql代表什么意思
0
if(len(key) != 0则加上AND pl.pickkey in (" + key + ")
也就是判断key的长度，如果长度不等于零就要加上这个条件
0
这是sql么？红色部分应该是sql模板，需要转换后才能用。

1.${if(len(key) == 0,"","AND pl.pickkey in (" + key + ")")}
if(len(key) == 0
空语句不执行
else
AND pl.pickkey in (" + key + ")
2.整体，三个或者四个 and 条件。
AND pl.status In ( 'new','part_pick')
AND pl.pickkey in (" + key + ")") 或没有
and rt.project_code = '${pkey}'
and rt.whse_code = '${wkey}'
