SQL SMO 生成插入語句不正確

Question

我正在使用 C# 應用程序來生成腳本。 我在下面有以下設置，但正在為其他模式生成表/插入語句。 我只想要一個特定的架構和其中的所有架構/數據。

我試圖設置options.WithDependencies = false; ，但它不會像編寫數據腳本那樣給我所需的一切。

我還缺少什么其他設置？

        private void GeneratingMainSQLScript(string schema)
        {
            Server srv = new Server(@".\sql2017");
            Database dbs = srv.Databases["SOURCE_T"];
            ScriptingOptions options = new ScriptingOptions();
            options.TargetServerVersion = SqlServerVersion.Version140;
            options.EnforceScriptingOptions = true;
            options.ScriptData = true;
            options.ScriptDrops = false;
            options.FileName = GenerateScriptFileName(schema, false);
            options.EnforceScriptingOptions = true;
            options.ScriptSchema = true;
            options.IncludeHeaders = true;
            options.AppendToFile = true;
            options.Indexes = true;
            options.WithDependencies = true;

            var tableNames = GetTableNames(schema);

            int progressCounter = 1;
            foreach (var tbl in tableNames)
            {
                if (tbl.SchemaName == "dbo" && tbl.TableName == "FileDatas")
                {
                    options.ScriptData = false;
                }

                dbs.Tables[tbl.TableName, tbl.SchemaName].EnumScript(options);

                DisplayDebug(string.Format("Running migration schema's ({2}) main genreated script | Total: {0} | Processing #: {1}", tableNames.Count, progressCounter, schema));

                progressCounter++;
            }
        }

更新：

在與我的領導合作后，我做出了這些改變，我們已經很接近了。 現在的問題：它是在創建表后生成 FKS，而不是像直接通過 SSMS 那樣在文件的末尾生成 FKS？

Server srv = new Server(@".\sql2017");
            Database dbs = srv.Databases["SOURCE_T"];
            ScriptingOptions options = new ScriptingOptions();
            options.FileName = GenerateScriptFileName(schema, isSchemaOnly);
            options.EnforceScriptingOptions = true;
      
            // start
            options.AnsiPadding = false;
            options.AppendToFile = true;
            options.ContinueScriptingOnError = false;
            options.ConvertUserDefinedDataTypesToBaseType = false;
            options.WithDependencies = false;
            options.IncludeHeaders = true;
            options.IncludeScriptingParametersHeader = false;
            options.SchemaQualify = true;
            options.Bindings = false;
            options.NoCollation = true;
            options.Default = true;
            options.ScriptDrops = false;
            options.ScriptSchema = isSchemaOnly;
            options.ExtendedProperties = true;
            options.TargetServerVersion = SqlServerVersion.Version140;
            options.TargetDatabaseEngineType = Microsoft.SqlServer.Management.Common.DatabaseEngineType.Standalone;
            options.LoginSid = false;
            options.Statistics = false;
            options.ScriptData = !isSchemaOnly;
            options.ChangeTracking = false;
            options.DriAllConstraints = true;
            options.ScriptDataCompression = false;
            options.DriForeignKeys = true;
            options.FullTextIndexes = false;
            options.Indexes = false;
            options.DriPrimaryKey = true;
            options.Triggers = false;
            options.DriUniqueKeys = true;
            options.DriAll = true;

Answer 1

這是我正在使用的解決方案。 這里的關鍵是我設置的所有選項，還有我如何提取表名。 GetTablesNames將按照需要制作的順序獲取表格，這允許所有內容與 FK 一起正確處理。

1. 正確獲取表格
2. 將此變量設置為 false： options.WithDependencies = false;

是我解決方案的關鍵。
