Verify – Compare Source and Target

The script scripts/compare_source_target.sql compares structure and high-level consistency between two databases without comparing row contents.

What is compared

Rowcounts per table
Columns: datatype, length, nullable, collation
Programmable objects: views, stored procedures, functions (hash of definition)
Triggers (hash of definition)
Users/Roles: principals existence + role memberships

How to run

Open scripts/compare_source_target.sql in SSMS
Set:
- @SourceDb (default: sysdb_UTF8)
- @TargetDb (default: sysdb_utf8_jr)
Execute.

Output style (quick to read)

Live messages (SSMS Messages tab)

You get a human-readable summary per step, e.g.:

ROWCOUNTS | SourceTables=... TargetTables=... TablesWithRowDiff=...
COLUMNS | ColumnDiffs=...
MODULES | Differences=...
TRIGGERS | Differences=...
PRINCIPALS | Differences=...
ROLEMEMBERS | Differences=...

At the end:

COMPARE_DONE | RowDiffTables=... | ColumnDiffs=... | ...

Result sets (details)

If differences exist, result sets are shown for:

Rowcount diffs
Column diffs
Module diffs
Trigger diffs
Principal diffs
Role membership diffs

If a section has no differences, you’ll see an ..._OK message and no detail list.
