Format SQL query in c++
I was wondering if there is something I can use in C++ similar to "sqlparse" module in Python to format my query. Do you know what can I use?
I'm sorry for didn't provide an example before. I want that something like this:
SELECT MEMB.NAME, MEMB.AGE, AGE.GROUP FROM MEMB, AGE WHERE MEMB.AGE = AGE.开发者_如何学JAVAAGE
Become this:
SELECT MEMB.NAME,
MEMB.AGE,
AGE.GROUP
FROM MEMB,
AGE
WHERE MEMB.AGE = AGE.AGE
Thanks a lot.
You can write your own pretty printer. In that case, it won't be any hard. Just replace things like the following:
"FROM" -> "\nFROM"
"WHERE" -> "\nWHERE"
"," -> ",\n\t"
"AND" -> "AND\n\t"
"OR" -> "OR\n\t"
etc.
Edit: as you don't code, here's a little version of this functionality.
#include <string>
using std::string; /* put these lines in the top of your file */
string replace(string a, string b, string c) {
unsigned x;
for(x = a.find(b); x != string::npos;) {
a.erase(x, b.length());
a.insert(x, c);
}
return a;
}
string formatSQL(string sql) {
replace(sql, "FROM", "\nFROM");
replace(sql, "WHERE", "\nWHERE");
replace(sql, "," , ",\n\t");
replace(sql, "AND", "AND\n\t");
replace(sql, "OR", "OR\n\t");
}
So calling formatSql("SELECT MEMB.NAME, MEMB.AGE, AGE.GROUP FROM MEMB, AGE WHERE MEMB.AGE = AGE.AGE")
gives you the desired result.
