IF condition in While loop in Snowflake procedure - snowflake-cloud-data-platform

Question

my procedure looks like below, but here, the values are not coming into if condition which is written in while loop. please let me know if someone fixes this. i am using v_CODE in insert command which is coming from if condition , since no values are coming into this V_CODE, procedure is getting failed and showing following error Undefined 'FCT.V_CODE'
`CREATE OR REPLACE PROCEDURE CDW_PROC.SAMPLE_PROCEDURE(col1 FLOAT, COL2 VARCHAR, COL3 VARCHAR, COL4 VARCHAR, COL5 VARCHAR, COL6 VARCHAR)

You have if/else structure based on the values coming for the SELECT query. So it is normal that the if/else part about v_CODE is not executed everything. For example if v_F_TIME_CUR equals to v_FILTER_DESC, then the following code will not be executed:
...
else if (v_CODE=='v_'+v_FILTER_DESC.trim())
{
v_CODE=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
}
I think you need to use separate "if" conditions?
if (v_BRAND == 'v_'+v_FILTER_DESC.trim())
{
v_BRAND=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
};
if ( v_F_TIME_CUR =='v_'+v_FILTER_DESC.trim())
{
v_F_TIME_CUR=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
};
if (v_F_TIME_PREV=='v_'+v_FILTER_DESC.trim())
{
v_F_TIME_PREV=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
};
...
if (v_CODE=='v_'+v_FILTER_DESC.trim())
{
v_CODE=v_FILTER_ATTRIBUTE+" "+v_FILTER_CONDITION+" "+v_FILTER_VALUE;
}
