 ## Architecture
@@ -45,33 +39,7 @@ Deploy using interactive script:
 ### Single-File Design
 The entire application logic resides in `jrunner/src/main/java/jrunner/jrunner.java`. This is a monolithic command-line tool with no abstraction layers or separate modules.
 
-### Dual Mode Operation (v1.1+)
-
-The tool operates in two modes:
-
-**Query Mode** (new in v1.1):
-- Activates automatically when destination flags are not provided
-- Outputs query results to stdout in CSV or TSV format
-- Silent operation - no diagnostic output, just clean data
-- Designed for piping to visidata, pspg, less, or other data tools
-- Format controlled by -f flag (csv or tsv)
-
-**Migration Mode** (original functionality):
-- Activates when destination flags are provided
-- Reads from source, writes to destination with batched INSERTs
-- Shows progress counters and timing information
-
 ### Data Flow
-
-**Query Mode:**
-1. Parse command-line arguments (-scu, -scn, -scp for source)
-2. Read SQL query from file specified by -sq flag
-3. Connect to source database via JDBC
-4. Execute source query and fetch results (fetch size: 10,000 rows)
-5. Output results to stdout in CSV or TSV format
-6. Close connection and exit
-
-**Migration Mode:**
 1. Parse command-line arguments (-scu, -scn, -scp for source; -dcu, -dcn, -dcp for destination)
 2. Read SQL query from file specified by -sq flag
 3. Connect to source and destination databases via JDBC
@@ -100,36 +68,23 @@ Command-line flags:
 - `-scu` - source JDBC URL
 - `-scn` - source username
 - `-scp` - source password
-- `-dcu` - destination JDBC URL (migration mode only)
+- `-dcu` - destination JDBC URL
-- `-dcn` - destination username (migration mode only)
+- `-dcn` - destination username

+- `-c` - clear target table before insert (default: true)
-- `-f` - output format: csv, tsv (query mode only, default: csv)
 
 ## Key Implementation Details
 
-### Mode Detection
+### Batch Size
-Query mode is automatically detected at runtime (line 131) by checking if all destination flags (dcu, dcn, dcp, dt) are empty. This allows seamless switching between query and migration modes without explicit mode flags.
+INSERT statements are batched at 250 rows (hardcoded at line 324). When the batch threshold is reached, sql is prepended with "INSERT INTO {table} VALUES" and executed.
-
-### Query Mode Output (v1.1+)
-Query mode uses dedicated output methods:
-- `outputQueryResults()` - Dispatches to format-specific methods
-- `outputCSV()` - RFC 4180 compliant CSV with proper quote escaping
-- `outputTSV()` - Tab-separated with tabs/newlines replaced by spaces
-- All output goes to stdout; no diagnostic messages in query mode
-- Helper methods: `escapeCSV()` and `escapeTSV()` for proper formatting
-
-### Batch Size (Migration Mode)
-INSERT statements are batched at 250 rows (hardcoded around line 324). When the batch threshold is reached, sql is prepended with "INSERT INTO {table} VALUES" and executed.
 
 ### Error Handling
 SQLException handling prints stack trace and exits immediately with System.exit(0). There is no transaction rollback or partial failure recovery.
 
 ### Performance Considerations
-- Result set fetch size is set to 10,000 rows (line 190)
+- Result set fetch size is set to 10,000 rows (line 173)
-- Progress counter prints with carriage return for real-time updates (migration mode only)
+- Progress counter prints with carriage return for real-time updates
-- Timestamps captured at start and end for duration tracking (migration mode only)
+- Timestamps captured at start (line 174) and end (line 368) for duration tracking
-- Query mode has no progress output to keep stdout clean for piping
