Concatenation Operator

You might also be interested in Concat helper.

Oracle concatenation is achieved in JavaScript using Template literal. Also it uses the Concat Helper to properly handle concatenations with nulls.

Oracle

IN -> Oracle_01.sql

--Additional Params: -t JavaScript
CREATE OR REPLACE PROCEDURE CONCAT_TEST
IS
NUM1 INTEGER := 123;
NUM2 INTEGER := 321;
VAR1 VARCHAR(10) := 'value';
concat_var VARCHAR(100);
sql_stmt VARCHAR(100);
BEGIN
    concat_var := NUM1 || NUM2 || VAR1 || 'literal';   
    sql_stmt := 'INSERT INTO t1 VALUES (''' || concat_var || ''')';    
    EXECUTE IMMEDIATE sql_stmt;
END;

SnowConvert helpers Code removed from the example. You can find them here.

OUT -> Oracle_01.sql

CREATE OR REPLACE PROCEDURE CONCAT_TEST ()
RETURNS STRING
LANGUAGE JAVASCRIPT
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"oracle"}}'
EXECUTE AS CALLER
AS
$$
    // SnowConvert Helpers Code section is omitted.

    let NUM1 = 123;
    let NUM2 = 321;
    let VAR1 = `value`;
    let CONCAT_VAR;
    let SQL_STMT;
    CONCAT_VAR = `${concatValue(NUM1)}${concatValue(NUM2)}${concatValue(VAR1)}literal`;
    SQL_STMT = `INSERT INTO t1
VALUES ('${concatValue(CONCAT_VAR)}')`;
    EXEC(SQL_STMT);
$$;
