}

插入表

- (BOOL)insertOneChannel:(NSString*)stime mytitle:(NSString*)stitle mycal:(NSString*)scal myruntime:(NSString*)sruntime

{

sqlite3_stmt *statement;

staticchar*sql = "INSERT INTO reports (id,stime,stitle,scal,sruntime) VALUES(NULL,?,?,?,?)";

//问号的个数要和(cid,title,imageData,imageLen)里面字段的个数匹配，代表未知的值，将在下面将值和字段关 联。

int success =sqlite3_prepare_v2(database_, sql, -1, &statement,NULL);

if (success !=SQLITE_OK) {

NSLog(@"Error: failed to insert:channels");

return NO;

}

//这里的数字1，2，3，4代表第几个问号

//sqlite3_bind_text(statement, 1, stime, -1, SQLITE_TRANSIENT);

char*p = [stime cStringUsingEncoding:1];

sqlite3_bind_text(statement,1, [stime cStringUsingEncoding:1], -1,SQLITE_TRANSIENT);

sqlite3_bind_text(statement,2, [stitle cStringUsingEncoding:1], -1,SQLITE_TRANSIENT);

sqlite3_bind_text(statement,3, [scal cStringUsingEncoding:1], -1,SQLITE_TRANSIENT);

sqlite3_bind_text(statement,4, [sruntime cStringUsingEncoding:1], -1,SQLITE_TRANSIENT);

success =sqlite3_step(statement);

sqlite3_finalize(statement);

if (success ==SQLITE_ERROR) {

NSLog(@"Error: failed to insert into the database with message.");

return NO;

}

NSLog(@"Insert One Channel#############:id = _");

return YES;

}

查询表

- (void) getChannels:(NSMutableArray*)fChannels{

sqlite3_stmt *statement =nil;

char*sql = "SELECT * FROM reports";

if (sqlite3_prepare_v2(database_, sql, -1, &statement,NULL) !=SQLITE_OK) {

NSLog(@"Error: failed to prepare statement with message:get channels.");

}

//查询结果集中一条一条的遍历所有的记录，这里的数字对应的是列值。
