Sqlite3綁定文本：傳遞字符串中的兩個值不起作用。

Question

productName = @"'Fidelity Bonds',Property'"; 
    regionName = @"'London',Paris',Tokyo'"; 
    yearName = @"'2007',2010'"; 

    sqlite3 *database; 
    const char *sqlStatement; 
    sqlite3_stmt *compiledStatement; 
    [self setPathForDatabase]; 

    if(sqlite3_open([storePath UTF8String], &database) == SQLITE_OK) 
    {   

     sqlStatement = "Select * from PorfolioPerformanceCPR where product_name IN (?) and region_name IN (?) and year_name IN (?) group by channel_name"; 

     if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) 
     {   
       sqlite3_bind_text(compiledStatement, 1, [productName UTF8String], -1, SQLITE_TRANSIENT); 
       sqlite3_bind_text(compiledStatement, 2, [regionName UTF8String], -1, SQLITE_TRANSIENT); 
       sqlite3_bind_text(compiledStatement, 3, [yearName UTF8String], -1, SQLITE_TRANSIENT); 
     } 

問題：當我在字符串productName，regionName和yearName中插入多個值時，代碼不起作用。需要幫忙。

Answer 1

看起來對我來說有可能是您的productName，regionName和yearName串內的一個引號一個問題：

productName = @"'Fidelity Bonds',Property'"; 
regionName = @"'London',Paris',Tokyo'"; 
yearName = @"'2007',2010'"; 

你試過：

productName = @"'Fidelity Bonds','Property'"; 
regionName = @"'London','Paris','Tokyo'"; 
yearName = @"'2007','2010'";
