Has this bug been resolved in the latest version of SQL Prompt?

Ok, thanks. This works for me.

Thanks for supplying the snapshot. It does look like dependencies- I loaded up your snapshot in your sample code and found that it was also scripting some tables.

Amending the options as I described earlier stops that - here's the correct line (notice it's the options at the point of building your 'work' that's important as the dependencies are included (or not) during the sync phase usually)

Code:

// Calculate the work to do using sensible default options
// The script is to be run on production so the runOnTwo parameter is true
work.BuildFromDifferences(stagingVsProduction, Options.IgnoreFileGroups | Options.IgnoreFillFactor | Options.IgnoreUserProperties | Options.IgnoreWhiteSpace | Options.IgnoreWithElementOrder | Options.IgnoreDatabaseAndServerName | Options.DecryptPost2kEncryptedObjects, true);

Sure- otherwise, it's probably just down to the objects that function relates to so a simple repro should also suffice track it down.

I can't provide the snapshot in the current shape. I'll have to strip the database and make a new snapshot.

RE: Difference list doesn't work

james.billings — Thu, 29 Nov 2012 13:51:49 GMT

OK, I tried your code here with defaults and a couple of functions and it only scripts the function that matches.

Is it possible for you to supply your snapshot as the problem you're seeing is likely to be rather dependent on the specifics of your DB. If so, please mail it to support@red-gate.com quoting F0067161 in the subject line.

Options.IgnoreDatabaseNames doesn't exists, so i tried IgnoreDatabaseName, but the option is obsolete, so i used the recomended option IgnoreDatabaseAndServerName.
I still receive a script with objects i don't want.

for example, the script want's to drop constraints on tables;
ALTER TABLE [dbo].[AGMG] DROP CONSTRAINT [PK_AGMG]

As you can see in the code fragment, I only select functions which start with a specific name.

RE: Difference list doesn't work

james.billings — Thu, 29 Nov 2012 12:08:48 GMT

IncludeDependencies is a default option. To turn it off you need to explicitly select all other defaults asides from that; so replace:

options.default

with

options.IgnoreFileGroups | options.IgnoreFillFactor | options.IgnoreUserProperties | options.IgnoreWhiteSpace | options.IgnoreWithElementOrder | options.IgnoreDatabaseNames | options.DecryptPost2kEncryptedObjects

RE: Difference list doesn't work

I can only select Options.IgnoreSynonymDependencies, but that doesn't work. The other option about dependecies is IncludeDependencies, there's no IgnoreDependencies option.

I'm trying to synchronise a list of table valued functions.

Here's a code fragment (in C#);

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using System.IO;
using System.Data;
using System.Data.SqlClient;
using System.Reflection;
using RedGate.SQLCompare.Engine;
using RedGate.Shared.SQL.ExecutionBlock;

namespace Config.DatabaseUpdate
{
class OltpFunctions
{

public static bool SyncOltpFunctionsToFile(string TargetCatalog, string TargetServer, int logType)
{
bool res = true;
string snapshotFile = Config.DataManager.ApplicationScriptPath() + "\\SnapshotProqOltp.snp";

using (Database stagingDB = new Database(),productionDB = new Database())
{
ConnectionProperties targetConnectionProperties = new ConnectionProperties(TargetServer, TargetCatalog);

// Connect to the two databases and read the schema
try
{
Logger.Log("Loading snapshot file", 2);
stagingDB.LoadFromDisk(snapshotFile);
}
catch (SqlException e)
{
Logger.Log(e.Message, logType);
res = false;
return res;
}
try
{
Logger.Log("Registering database " + targetConnectionProperties.DatabaseName, 2);
productionDB.Register(targetConnectionProperties, Options.Default);
}
catch (SqlException e)
{
Logger.Log(e.Message, logType);
res = false;
return res;
}

// Compare snapshot to production. Comparing in this order makes production the second database
Differences stagingVsProduction = stagingDB.CompareWith(productionDB, Options.IgnoreSynonymDependencies);

// Select the differences to include in the synchronization. In this case, we're using all differences.
foreach (Difference difference in stagingVsProduction)
{
difference.Selected = false;

// Only select functions
if (difference.DatabaseObjectType == ObjectType.Function)
{
// only fix differences or create new objects in the target database
if ((difference.Type == DifferenceType.Different) || (difference.Type == DifferenceType.OnlyIn1))
{
// Only select objects which start with Dim, Fact, Etl or Sec
if ((difference.Name.ToUpper().StartsWith("[DBO].[DIM")) || (difference.Name.ToUpper().StartsWith("[DBO].[FACT")) || (difference.Name.ToUpper().StartsWith("[DBO].[ETL")) || (difference.Name.ToUpper().StartsWith("[DBO].[SEC")))
{
Logger.Log(string.Format("Selected objectname: {0}", difference.Name), 6);
difference.Selected = true;
}
}
}
}

Work work = new Work();

// Calculate the work to do using sensible default options
// The script is to be run on production so the runOnTwo parameter is true
work.BuildFromDifferences(stagingVsProduction, Options.Default, true);

// We can now access the messages and warnings
Logger.Log("Messages:", logType);

foreach (Message message in work.Messages)
{
Logger.Log(message.Text, logType);
}

Logger.Log("Warnings:", logType);

foreach (Message message in work.Warnings)
{
Logger.Log(message.Text, logType);
}

// Disposing the execution block when it's not needed any more is important to ensure
// that all the temporary files are cleaned up
using (ExecutionBlock block = work.ExecutionBlock)
{
// Display the SQL used to synchronize
Logger.Log("SQL to synchronize:", logType);
Logger.Log(block.GetString(), logType);

// Finally, use a BlockExecutor to run the SQL against the WidgetProduction database
try
{
//BlockExecutor executor = new BlockExecutor();
//executor.ExecuteBlock(block, targetConnectionProperties.ServerName, targetConnectionProperties.DatabaseName);

// Write the sql block to a file.
DataManager.FileWriter(block.GetString(), @"D:\Temp\SqlToSync.sql");
}
catch (SqlException e)
{
Logger.Log(e.Message, 2);
res = false;
return res;
}
return res;
}
}
}

}
}

The last time I tried this it seemed to work okay. One possibility is if the objects being included are dependencies of others - is this the case? If so, you may need to set the option to not include dependencies.

Failing that, can you post back a code sample of how you've got it set up and details of the assembly versions you're referencing so I can try it out here?

Difference list doesn't work

njansen — Tue, 27 Nov 2012 15:07:23 GMT

I'm building a tool to sync a specific list of objects
For each object i want to sync i'll set the Difference.Selected property to true, for all other objects i don't want to sync, i'll set the Difference.Selected property to false.

After that, i'll call the Work.BuildFromDifferences method;
Work.BuildFromDifferences(Differences, Options.Default, true);

Why do i see objects where the Difference.Selected prop is set the false?

Skip compare, migrate all rows

schammer — Thu, 26 Apr 2012 16:37:28 GMT

I would like to migrate data into an empty database with the same schema as the source. Since I know there will never be data in the destination, is there a way to skip the CompareDatabases() call and force the GetMigrationSQL() step to generate INSERT statements for all rows in the source database?

I ask because the CompareDatabases() call can take a long time on larger databases (20GB+), which seems unnecessary given that we know the destination is empty and there's nothing to compare to.

Thanks!
Brian

RE: Order of tables in synchronization script (data compare)

james.billings — Wed, 29 Feb 2012 16:05:25 GMT

Thanks for your post - you may have trouble unfortunately. There's no easy way to control the ordering in the way you suggest, as our sync scripts are designed to work by disabling all FK's first, inserting/updating/deleting as appropriate, then re-enabling again.

If you can work out a correct order to do things that satisfies the keys then potentially you could work with one table at a time; but it's likely to get a bit messy...
