Question

我正在尝试创建数据库和相关表。一切都有效，除了'EmployeeDocuments'表（数据库和4个表创建）。它给出了一个错误：

数据库中已有一个名为“FK_Employees_Companies1”的对象。

我的代码如下：

private void UserEntryForm_Activated(object sender, EventArgs e)
    {
        CheckIfDBExist();
    }
    int i;

    private void CheckIfDBExist()
    {

        SqlConnection tmpConn = new SqlConnection("server=(local)\\SQLEXPRESS;user=sa;pwd=123");

        string sqlCreateDBQuery = string.Format("if not exists (select name from sys.databases where name = 'Devrimer_v2222')create database Devrimer_v2222");

        SqlCommand sqlCmd = new SqlCommand(sqlCreateDBQuery, tmpConn);

        string constr = Tools.Baglanti.ConnectionString.ToString();

        try
        {
            tmpConn.Open();
            int sonuc = sqlCmd.ExecuteNonQuery();

            if (sonuc != 0) 
            {
                tmpConn.Close();

                string query = "if not exists(select * from sys.tables where name = 'Companies' ";

Answer 1

这是因为你在创建表之前检查表是否存在，但是你总是尝试创建约束而不管它们是否存在，你有类似的东西：

IF NOT EXISTS (SELECT * FROM sys.tables WHERE name = 'Employees')
    CREATE TABLE dbo.Employees (....)
ALTER TABLE dbo.Employees WITH CHECK ADD CONSTRAINT ....

使用这种语法，只有紧随IF之后的语句才是有条件的，一个简单的例子就是：

IF 1 = 0
PRINT '1';
PRINT '2';

这将简单地打印＆＃34; 2＆＃34;。如果要有条件地执行多个语句，则需要将它们包装在语句块中（BEGIN/END）

IF NOT EXISTS (SELECT * FROM sys.tables WHERE name = 'Employees')
BEGIN
    CREATE TABLE dbo.Employees (....)
    ALTER TABLE dbo.Employees WITH CHECK ADD CONSTRAINT ....
END

对于它的价值，您可以使用逐字字符串文字来使所有内容更易读（并且更容易编辑）。 e.g。

string query = @"IF NOT EXISTS (SELECT * FROM sys.tables WHERE name = 'Employees')
                BEGIN
                    CREATE TABLE dbo.Employees (....)
                    ALTER TABLE dbo.Employees WITH CHECK ADD CONSTRAINT ....
                END;";

Answer 2

尝试更改约束名称，似乎是在数据库中使用相同名称创建的

Answer 3

我使用了MyDbUtils.exe并导出了所有过程和触发器，并包含了表和数据库创建的语法，它工作得非常好;

我使用了一个方法（SQLTEXTexec（））来运行所有文本字符串：

然后; 使用CheckIfDBExist（））方法创建数据库和表; 到目前为止工作正常 ;

private void SQLTEXTexec(string sql, SqlConnection conn)
        {
            string sqlBatch = string.Empty;
            SqlCommand cmd = new SqlCommand(string.Empty, conn);
            conn.Open();
            sql += "\nGO";   // make sure last batch is executed.
            try
            {
                foreach (string line in sql.Split(new string[2] { "\n", "\r" }, StringSplitOptions.RemoveEmptyEntries))
                {
                    if (line.ToUpperInvariant().Trim() == "GO")
                    {
                        cmd.CommandText = sqlBatch;
                        cmd.ExecuteNonQuery();
                        sqlBatch = string.Empty;
                    }
                    else
                    {

                    }
                }
            }
            finally
            {
