问题描述
我将 sqlite3.c:34147:42: error: ‘mremap’ undeclared here (not in a function); did you mean ‘munmap’?
{ "mremap",(sqlite3_syscall_ptr)mremap,0 },^~~~~~
munmap
sqlite3.c: In function ‘unixRemapfile’:
sqlite3.c:38766:42: error: ‘MREMAP_MAYMOVE’ undeclared (first use in this function)
pNew = osMremap(pOrig,nReuse,nNew,MREMAP_MAYMOVE);
^~~~~~~~~~~~~~
sqlite3.c:38766:42: note: each undeclared identifier is reported only once for each function it appears in
sqlite3.c:38766:42: warning: passing argument 4 of ‘(void * (*)(void *,size_t,int,...))aSyscall[24].pCurrent’ makes integer from pointer without a cast [-Wint-conversion]
sqlite3.c:38766:42: note: expected ‘int’ but argument is of type ‘struct unix_syscall *’
列的一些数据整理如下：
name我需要的是所有的中文单词，我们不需要英文单词和'-'，但不是所有的值都带有 `select name from temp_test`
name
1 ABCD-你好吗
2 CDEF-我很好
3 IDFASGASD-你好
4 你好
和英文单词，所以我不能使用下面的sql，是有谁知道如何实现它？
-解决方法
最后，我通过下面的 SQL 解决了我的问题
SELECT CASE WHEN b.name LIKE '%-%'
THEN SPLIT_PART(b.name,'-',2)
ELSE b.name END FROM temp_project a
left join temp_test b
on a.id=b.id and a.time = b.time;
