+title: SQL API
+description: Get started with SQL API in LocalStack for Snowflake
+tags: ["Base"]
+---
+
+## Introduction
+
+The [Snowflake SQL API](https://docs.snowflake.com/en/developer-guide/sql-api/about-sql-api) allows you to submit SQL statements for execution over HTTP. LocalStack for Snowflake supports the SQL API, enabling you to execute single or multiple SQL statements locally.
+
+## Multi-Statement Execution
+
+The Snowflake emulator supports [submitting multiple SQL statements in a single request](https://docs.snowflake.com/en/developer-guide/sql-api/submitting-multiple-statements). Separate each statement with a semicolon (`;`) and specify the statement count using one of the following methods:
+
+### Session-level configuration
+
+Set `MULTI_STATEMENT_COUNT` in the session parameters. This setting is persistent for the entire session. When set to `0`, the emulator accepts any number of statements without requiring an exact count. If set to a non-zero value, you must specify exactly that many statements in each batch.
+
+```python showLineNumbers
+conn = snowflake.connector.connect(
+    user="test",
+    password="test",
+    account="test",
+    host="snowflake.localhost.localstack.cloud",
+    session_parameters={"MULTI_STATEMENT_COUNT": 0}
+)
+
+with conn.cursor() as cur:
+    cur.execute("SELECT 1; SELECT 2; SELECT 3")
+    print(list(cur))  # First result
+    cur.nextset()
+    print(list(cur))  # Second result
+```
+
+### Request-level configuration
+
+Specify `num_statements` per query using the Python connector's `execute()` method.
+
+```python showLineNumbers
+with conn.cursor() as cur:
+    cur.execute("SELECT 1; SELECT 2; SELECT 3", num_statements=3)
+    print(list(cur))  # First result
+    cur.nextset()
+    print(list(cur))  # Second result
+```
+
+If `MULTI_STATEMENT_COUNT` does not match the actual number of statements, an error is returned:
+
+```
+Actual statement count <actual_count> did not match the desired statement count <desired_count>.
+```
