Pull Request Overview

This PR introduces support for a new Vector data type and includes several DesignMode fixes. Key changes include:

• Adding Vector handling across core code (SqlSmoObject, DataType, ParamBase, DataEnumerator) with associated default settings and type converters.
• Updating QueryStoreOptions to support DesignMode and improving error handling.
• Enhancing unit tests, test frameworks, and documentation to reflect the new support for Vector data types.

• Using newValue.Value directly may lead to a null reference if queryCaptureModeProp.Value is null. Consider adding a null-check or providing a default value before accessing .Value.

queryStoreCaptureModeTypeConverter.ConvertToInvariantString(newValue.Value)));

src/Microsoft/SqlServer/Management/Smo/DataType.cs:125

• [nitpick] The default MaximumLength for Vector is hardcoded to 1998; ensure this value is appropriate for all expected scenarios or consider making it configurable.

this.MaximumLength = 1998;

src/Microsoft/SqlServer/Management/Smo/DataEnumerator.cs:963

• The calculation for Vector dimensions may throw unexpected results if columnData.MaxLength is less than 8; verify that such a scenario is impossible or add validation to guard against it.

int dimensions = (columnData.MaxLength - 8) / 4;

src/FunctionalTest/Smo/ScriptingTests/Table_SmoTestSuite.cs:4082

• [nitpick] The condition used to determine when to include a Vector column in tests may be ambiguous; please double-check that it correctly targets the intended server configurations.
