The result is written into the ** buffer supplied as the second parameter whose size is given by ** the first parameter. Note that the order of the ** first two parameters is reversed from snprintf().)^ This is an ................................................................................ ** guarantees that the buffer is always zero-terminated. ^The first ** parameter "n" is the total size of the buffer, including space for ** the zero terminator. So the longest string that can be completely ** written will be n-1 characters. ** ** ^The sqlite3_vsnprintf() routine is a varargs version of sqlite3_snprintf(). ** ** These routines all implement some additional formatting ** options that are useful for constructing SQL statements. ** All of the usual printf() formatting options apply. In addition, there ** is are "%q", "%Q", "%w" and "%z" options. ** ** ^(The %q option works like %s in that it substitutes a nul-terminated ** string from the argument list. But %q also doubles every '\'' character. ** %q is designed for use inside a string literal.)^ By doubling each '\'' ** character it escapes that character and allows it to be inserted into ** the string. ** ** For example, assume the string variable zText contains text as follows: ** ** <blockquote><pre> ** char *zText = "It's a happy day!"; ** </pre></blockquote> ** ** One can use this text in an SQL statement as follows: ** ** <blockquote><pre> ** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText); ** sqlite3_exec(db, zSQL, 0, 0, 0); ** sqlite3_free(zSQL); ** </pre></blockquote> ** ** Because the %q format string is used, the '\'' character in zText ** is escaped and the SQL generated is as follows: ** ** <blockquote><pre> ** INSERT INTO table1 VALUES('It''s a happy day!') ** </pre></blockquote> ** ** This is correct. Had we used %s instead of %q, the generated SQL ** would have looked like this: ** ** <blockquote><pre> ** INSERT INTO table1 VALUES('It's a happy day!'); ** </pre></blockquote> ** ** This second example is an SQL syntax error. As a general rule you should ** always use %q instead of %s when inserting text into a string literal. ** ** ^(The %Q option works like %q except it also adds single quotes around ** the outside of the total string.

The result is written into the ** buffer supplied as the second parameter whose size is given by ** the first parameter. Note that the order of the ** first two parameters is reversed from snprintf().)^ This is an ................................................................................ ** guarantees that the buffer is always zero-terminated. ^The first ** parameter "n" is the total size of the buffer, including space for ** the zero terminator. So the longest string that can be completely ** written will be n-1 characters. ** ** ^The sqlite3_vsnprintf() routine is a varargs version of sqlite3_snprintf(). ** ** These routines all implement some additional formatting ** options that are useful for constructing SQL statements. ** All of the usual printf() formatting options apply. In addition, there ** is are "%q", "%Q", "%w" and "%z" options. ** ** ^(The %q option works like %s in that it substitutes a nul-terminated ** string from the argument list. But %q also doubles every '\'' character. ** %q is designed for use inside a string literal.)^ By doubling each '\'' ** character it escapes that character and allows it to be inserted into ** the string. ** ** For example, assume the string variable zText contains text as follows: ** ** <blockquote><pre> ** char *zText = "It's a happy day!"; ** </pre></blockquote> ** ** One can use this text in an SQL statement as follows: ** ** <blockquote><pre> ** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText); ** sqlite3_exec(db, zSQL, 0, 0, 0); ** sqlite3_free(zSQL); ** </pre></blockquote> ** ** Because the %q format string is used, the '\'' character in zText ** is escaped and the SQL generated is as follows: ** ** <blockquote><pre> ** INSERT INTO table1 VALUES('It''s a happy day!') ** </pre></blockquote> ** ** This is correct. Had we used %s instead of %q, the generated SQL ** would have looked like this: ** ** <blockquote><pre> ** INSERT INTO table1 VALUES('It's a happy day!'); ** </pre></blockquote> ** ** This second example is an SQL syntax error. As a general rule you should ** always use %q instead of %s when inserting text into a string literal. ** ** ^(The %Q option works like %q except it also adds single quotes around ** the outside of the total string. Additionally, if the parameter in the ** argument list is a NULL pointer, %Q substitutes the text "NULL" (without ** single quotes).)^ So, for example, one could say: ** ** <blockquote><pre> ** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES(%Q)", zText); ** sqlite3_exec(db, zSQL, 0, 0, 0); ** sqlite3_free(zSQL); ** </pre></blockquote> ** ** The code above will render a correct SQL statement in the zSQL ** variable even if the zText variable is a NULL pointer. ** ** ^(The "%w" formatting option is like "%q" except that it expects to ** be contained within double-quotes instead of single quotes, and it ** escapes the double-quote character instead of the single-quote ** character.)^ The "%w" formatting option is intended for safely inserting ** table and column names into a constructed SQL statement. ** ** ^(The "%z" formatting option works like "%s" but with the ** addition that after the string has been read and copied into ** the result, [sqlite3_free()] is called on the input string.)^ */ SQLITE_API char *sqlite3_mprintf(const char*,...); SQLITE_API char *sqlite3_vmprintf(const char*, va_list); SQLITE_API char *sqlite3_snprintf(int,char*,const char*, ...); SQLITE_API char *sqlite3_vsnprintf(int,char*,const char*, va_list); /* ................................................................................ ** a schema change, on the first [sqlite3_step()] call following any change ** to the [sqlite3_bind_text | bindings] of that [parameter]. ** ^The specific value of WHERE-clause [parameter] might influence the ** choice of query plan if the parameter is the left-hand side of a [LIKE] ** or [GLOB] operator or if the parameter is compared to an indexed column ** and the [SQLITE_ENABLE_STAT3] compile-time option is enabled. ** </li> ** ** <p>^sqlite3_prepare_v3() differs from sqlite3_prepare_v2() only in having ** the extra prepFlags parameter, which is a bit array consisting of zero or ** more of the [SQLITE_PREPARE_PERSISTENT|SQLITE_PREPARE_*] flags. ^The ** sqlite3_prepare_v2() interface works exactly the same as ** sqlite3_prepare_v3() with a zero prepFlags parameter. ** </ol> */ SQLITE_API int sqlite3_prepare( sqlite3 *db, /* Database handle */ const char *zSql, /* SQL statement, UTF-8 encoded */ int nByte, /* Maximum length of zSql in bytes. */ sqlite3_stmt **ppStmt, /* OUT: Statement handle */ const char **pzTail /* OUT: Pointer to unused portion of zSql */ ................................................................................ ** wal file in wal mode databases, or the number of pages written to the ** database file in rollback mode databases.
