Mastering Snowflake Stored Procedures for Beginners: A Comprehensive Guide (2024)

FAQs

What is $$ in Snowflake procedure? ›

In the body of the stored procedure (the AS clause), you use a Snowflake Scripting block. If you are creating a Snowflake Scripting procedure in SnowSQL or the Classic Console, you must use string literal delimiters ( ' or $$ ) around the body of the stored procedure.

Modifies the properties for an existing stored procedure. If you need to make any changes not supported here, use DROP PROCEDURE instead and then recreate the stored procedure.

Snowflake does not completely validate the code when you execute the CREATE PROCEDURE command. For example, for Snowpark (Scala) stored procedures, the number and types of input arguments are validated, but the body of the function is not validated.

How does it work? You start by naming your CTE and optionally specifying the names of its columns. Then, you write a SQL query (usually a SELECT ) that fills the CTE with data. This data acts just like a table, which you can use in the rest of your SQL statement.

Procedure is a block of PL/SQL code , it never stored in database. Procedure is a block of PL/SQL code , it is named and stored within the database. Stored procedure is block of PL/SQL code it is named and stored within the database. someone saying procedure concepts from Oracle for PL/SQL .

This is because a Snowflake stored procedure returns a maximum of 1 value or 1 table. Therefore Snowflake is unable to return multiple 'result sets' in multiple result tabs the way Teradata does. But you can use query history down in the query results section to tab through multiple query resultsets in a worksheet.

LANGUAGE SQL: Since Snowflake supports multiple languages for stored procedures, this parameter specifies the language used. For Snowflake javascript, the value is javascript (it can be either Java, Python, Snowflake Scripting (SQL), or Scala)

A task can execute any one of the following types of functions: Single SQL statement. Call to a stored procedure. Procedural logic using Snowflake Scripting.

Can we rename the procedure in Snowflake? ›

in Snowflake you can't really ALTER a procedure. All you can do with an ALTER is renaming or changing the comment.

Use SQL Server Management Studio

In Object Explorer, connect to an instance of Database Engine and then expand that instance. Expand Databases, expand the database in which the procedure belongs, and then expand Programmability. Expand Stored Procedures, right-click the procedure to remove, and then select Delete.

In the body of Snowflake's Javascript Stored Procedures or Functions, the double dollar sign $$ denotes the Start and End of the Javascript code block.

Similar to other database objects (tables, views, UDFs, etc.), stored procedures are owned by a role and have one or more privileges that can be granted to other roles. Currently, the following privileges apply to stored procedures: USAGE. OWNERSHIP.

$$ is the id of the current process. Every process in a UNIX like operating system has a (temporarily) unique identifier, the PID. No two processes running at the same time can have the same PID, and $$ refers to the PID of the bash instance running the script.

Two dollar signs( $$) are used for Dollar quoting. Anywhere in PostgreSQL, we can use it to replace the single quotes around string literals (constants). Such a string literal occurs to be the body of a function. A series of zero or more characters in single quotation marks is a string literal.

$$ is used to reference the process ID of bash shell itself. $# $# is quite a special bash parameter and it expands to a number of positional parameters in decimal. $0. $0 bash parameter is used to reference the name of the shell or shell script.

$$PLSQL_UNIT : The name of the current PL/SQL program unit.
