This example declares a variable named profit for use in a Snowflake Scripting anonymous block: DECLARE profit number(38, 2) DEFAULT 0.0; BEGIN LET cost number(38, 2) := 100.0; LET revenue number(38, 2) DEFAULT 110.0; profit := revenue - cost; RETURN profit; END; Note: If you...
Since SQL variables are limited to a maximum size of 256 characters, you must use a scripting block rather than a SQL variable. DECLARE -- In the code below, $$ is the multiline string delimiter. -- $$ lets us include newlines, single and double quotes -- without needing to escape ...
For a comparison of the TO_QUERY function with dynamic SQL, see Constructing SQL at runtime. Example of using a bind variable to set the value of a property The following stored procedure uses the comment argument to add a comment for a table in a CREATE TABLE statement. In the statement...
This example demonstrates how an SQL collation uses different sorting rules for the non-Unicode strings. The query output shows the different sort orders for the same values encoded as the Unicode/non-Unicode e.g. SQL Collation sorts a non-Unicode “Mountain BIke A-F100” before “Mountain BIk...
In this scenario, more than one connection is trying to insert a unique combination ofShipperIdandIdentifierValueinto the table. Only one “unique” insert is allowed and that is enforced by the Unique constraint on the two columns. I’ll be executing the query from the context of the two ...
A RESULTSET or CURSOR does not necessarily cache all the rows of the result set at the time that the query is executed. FETCH operations can experience latency.Examples FETCH my_cursor_name INTO my_variable_name ; For a more complete example of using a cursor, see the introductory cursor...
When you execute SQL in anEXECUTE IMMEDIATEcommand or anOPEN command for a cursor, you can bind variables with the USING clause. This example binds variables in an EXECUTE IMMEDIATE command with a USING clause: EXECUTE IMMEDIATE:queryUSING(minimum_price,maximum_price); ...
from the conn. str. and see what happens. The second interesting thing is the way the “execute” method executes the query(RPC call, parameterized batch request). More on the two topics can be foundhere(Data Providers and User Options) andhere(Client Requests and SQL Events in SQL Server...
With the testCollation database set to use SQL_Latin1_General_CP1_CI_AS, we have the following output. Figure 4, SQL collation and sub-optimal plan So, the client code executes a parameterized batch. It then passes a Unicode parameter value “Goldberg“. The query executes in the context...
Within the FOR loop, references to i resolve to the loop counter variable (not to the variable declared outside of the loop). CREATE PROCEDURE p(iteration_limit INTEGER) RETURNS VARCHAR LANGUAGE SQL AS $$ DECLARE counter INTEGER DEFAULT 0; i INTEGER DEFAULT -999; return_value VARCHAR DEFAULT...
