SQLite 查询语句插入在 swift 中无法正常工作

问题描述

我正在调用一个插入查询语句，以便在 sqlite 文件的 tc_devices 中插入数据。但在 XCode 中，我在控制台中得到输出：无法插入行。

这里是 CreateTable 查询语句：-

"CREATE TABLE IF NOT EXISTS tc_devices (id INTEGER NOT NULL UNIQUE,name TEXT NOT NULL UNIQUE,uniqueid TEXT NOT NULL,lastupdate DATETIME DEFAULT NULL,positionid INTEGER DEFAULT NULL,groupid INTEGER DEFAULT NULL,attributes TEXT DEFAULT TEXT DEFAULT NULL,model TEXT DEFAULT NULL,contact TEXT DEFAULT NULL,category TEXT DEFAULT NULL,disabled BLOB DEFAULT '0');"

    let db = connectDatabase(fileName: "Contact.sqlite")
    let sqlITE_TRANSIENT = unsafeBitCast(-1,to: sqlite3_destructor_type.self)

    let insertStatementString = "INSERT INTO tc_devices (id,name,uniqueid,lastupdate,positionid,groupid,attributes,phone,model,contact,category,disabled) VALUES (?,?,?);"
    //        var insertStatementQuery: OpaquePointer?
    var insertStatementQuery: OpaquePointer? = nil
    
    let uniqueid = Utility.getUDID()
    let phoneno =  UserDefaults.standard.object(forKey: "UserMobileNo") as! String
    
    if(sqlite3_prepare_v2(db,insertStatementString,-1,&insertStatementQuery,nil)) == sqlITE_OK{
        
        sqlite3_bind_int(insertStatementQuery,1,Int32(devideId))
        sqlite3_bind_text(insertStatementQuery,2,(name as Nsstring).utf8String,sqlITE_TRANSIENT)
        sqlite3_bind_text(insertStatementQuery,3,(uniqueid as Nsstring).utf8String,4,(currentTime as Nsstring).utf8String,sqlITE_TRANSIENT)
        sqlite3_bind_int(insertStatementQuery,5,Int32(0))
        sqlite3_bind_int(insertStatementQuery,6,Int32(0))
        sqlite3_bind_text(insertStatementQuery,7,nil,8,(phoneno as Nsstring).utf8String,9,10,11,12,"0",sqlITE_TRANSIENT)
        
        if sqlite3_step(insertStatementQuery) == sqlITE_DONE {
            print("Successfully inserted row.")
        } else {
            print("Could not insert row.")
        }
    } else {
        print("INSERT statement Could not be prepared.")
    }
    sqlite3_finalize(insertStatementQuery)
