Redis command execution failed, sql=${originalSql}

Error message

Redis command execution failed, sql=${originalSql}

What it means

Thrown by RedisScriptExecutor.executeCommand as an IllegalStateException wrapping a SQLException from doExecuteCommand. This occurs when the underlying Redis JDBC driver rejects the command during query execution (stmt.execute at line 222). The original SQL is included in the message for diagnosis. This is a wrapper that preserves the SQLException as the cause.

Solutions

1. Catch IllegalStateException at the call site and surface the cause SQLException to the user
2. Validate the Redis command syntax before execution
3. Check that the key exists and its type matches the query before calling executeSelectTable

Example fix

// before
List<ExecuteResponse> results = executor.execute(command);

// after
try {
    List<ExecuteResponse> results = executor.execute(command);
} catch (IllegalStateException e) {
    log.error("Redis command failed: {}", e.getMessage(), e.getCause());
    // surface user-facing error
}

// No pre-validation can fully prevent runtime SQLExceptions from the Redis driver.
// Ensure the key exists and its type matches before calling executeSelectTable:
String keyType = executor.getKeyType(command.getTableName());
if (keyType == null || "none".equalsIgnoreCase(keyType)) {
    // key does not exist; skip execution
}

try {
    List<ExecuteResponse> results = executor.execute(command);
} catch (IllegalStateException e) {
    log.error("Redis command failed: {}", e.getMessage());
    Throwable cause = e.getCause(); // original SQLException
    // surface to user
}

When it happens

Trigger: Calling RedisScriptExecutor.execute or executeSelectTable where doExecuteCommand throws SQLException. This happens when stmt.execute() at line 222 fails — e.g., the Redis JDBC driver reports a syntax error, the key does not exist for a type-specific query, or the connection is broken.

Common situations: Invalid Redis command syntax; querying a key whose type does not match the expected script; connection dropped mid-execution; Redis JDBC driver version incompatibility.
