It is not available in MySQL or SQL Server. Someone could tell me what could be wrong, I have been trying to solve it for several days but without success. Decode SQL Decode Function in SQL - DECODE is a function in Oracle and is also used to provide if-then-else type of logic to SQL. In the case of CASE all the complete statement without the alias. I have searched the internet for a solution and in many cases I read that I must leave out of the GROUP BY the aggregation field in this case SUM (fac_neto) but for the other two fields CLT_NOMBRE1 and DECODE (MELO) I must include them there. search The value that is compared against expression. This key-mapper must implement the CacheKeyMapper interface. It is automatically converted to the data type of the first search value before comparing. If an application needs greater control over the way in which Oracle Coherence keys are mapped to Oracle NoSQL Database Key objects, the cache can be configured with a key-mapper, which can provide arbitrary translation of key types. s1, s2,, or sn is the expression to search for. , ,sn,rn, d) Code language: SQL (Structured Query Language) (sql) In this syntax: e is the argument that to be searched for or compared with other argument s1, s2, sn. , default ) Parameters or Arguments expression The value to compare. Syntax and Parameters: The basic syntax for writing DECODE function in SQL is as follows: DECODE ( expression, search1, result1, search2, result2. The following illustrates the syntax of the SQL DECODE () function: DECODE (e, s1, r1, s2, r2. 00000 - "group function is not allowed here."Įrror in row: 18 Column: 6 SELECT CLT_NOMBRE1, -name of customerĭECODE(zpk, NULL, MAX(zpk) OVER (PARTITION BY factura_ha, facturanumero,locacion) MELO,ĭECODE(zpk, NULL, MAX(zpk) OVER (PARTITION BY factura_ha, facturanumero,locacion) The Oracle decode and case functions are used within the Oracle database to transform data values for one value to another. Syntax The syntax for the DECODE function in Oracle/PLSQL is: DECODE ( expression, search, result, search, result. The problem occurs with the SUM function when I try to run the query I get the following error: I call this data from a table of invoice data. Syntax: DECODE (expr1,expr2,result 1, result2) If expr1 equals to expr2 then decode functions returns Result 1 otherwise Result 2 as output. If it is not clear the let's understand with the DECODE() Examples.I have the following query where I am selecting the customer number, I do a DECODE where I have the measurement data of the location and the sum of the net value of the invoice in a SUM function. Oracle automatically converts the return value to the same data type as the first result. The first parameter is your main value or it can be your table value.Second parameter is search value which mean that second parameter value matchs with the first parameter value if it is match then third parameter return their value otherwise fourth parameter returns their value. , default ) In your example In the first DECODE 2 is the expression the next 2 is what the first 2 will be compared to the next DECODE is the result if 2 2 In the second DECODE 3 is the expression It is compared to the 7 and the 4.

In the DECODE() function, We pass four parameter. The syntax is DECODE ( expression, search, result, search, result. Let's understand the syntax so we can easily use the DECODE() function in Oracle SQL. Syntax of DECODE() function in OracleĭECODE(value,search_value,result,default_value) Oracle DECODE function is used in different database versions like Oracle 9i,Oracle 10g,Oracle 11g and Oracle 12c. Oracle DECODE only use for equality check logic in Oracle SQL. Oracle DECODE is use for transform the data to one value to another value. Oracle DECODE is a function in Oracle which help to implement if-then-else logic in SQL query. Because the first argument equals the second one. In this Oracle SQL Tutorial, We will expolre the DECODE() function in Oracle. In this example, the DECODE() function compares the first argument (one) with the second argument (also one).
