How do I perform the EXEC task in a "loop" with MSBuild ItemGroups?

How do I perform the EXEC task in a "loop" with MSBuild ItemGroups?

Instead of repeating this command over and over, like so:

    <Exec ContinueOnError="false" Command="sqlcmd -S $(ServerName) $(SqlServerUser) -d $(DbName) -v TableName=%22account%22 -i data\add_sql_cache.sql -b" />
    <Exec ContinueOnError="false" Command="sqlcmd -S $(ServerName) $(SqlServerUser) -d $(DbName) -v TableName=%22services%22 -i data\add_sql_cache.sql -b" />
    <Exec ContinueOnError="false" Command="sqlcmd -S $(ServerName) $(SqlServerUser) -d $(DbName) -v TableName=%22servicesGroup%22 -i data\add_sql_cache.sql -b" />
    <Exec ContinueOnError="false" Command="sqlcmd -S $(ServerName) $(SqlServerUser) -d $(DbName) -v TableName=%22servicesCategory%22 -i data\add_sql_cache.sql -b" />

I'd rather define an ItemGroup and just execute a "loop". I've got the ItemGroup down:

<ItemGroup>
    <CachedTables Include="account" />
    <CachedTables Include="services" />
    <CachedTables Include="servicesGroup" />
    <CachedTables Include="servicesCategory" />

But due to MSBuild's amazingly unintuitive syntax, I have no idea how to perform the Exec task in a loop with the ItemGroup above as an input.
