![]() ![]() ![]() V_encoded_string VARCHAR2(4000) := 'SGVsbG8sIFdvcmxkIQ=' You can replace 'Hello, World!' with your own input string. The encoded string is stored in the v_encoded_string variable. In the above example, the UTL_RAW.CAST_TO_RAW function converts the input string to a raw format, and then the UTL_ENCODE.BASE64_ENCODE function encodes the raw data into Base64 format. V_encoded_string := UTL_ENCODE.BASE64_ENCODE(UTL_RAW.CAST_TO_RAW(v_input_string)) V_input_string VARCHAR2(4000) := 'Hello, World!' Here’s an example of how you can encode and decode data in Base64 format: In Oracle, you can perform Base64 encoding and decoding using the UTL_ENCODE and UTL_RAW packages. If you need to encode or decode larger data, you might need to split the input into smaller chunks and perform the encoding or decoding operation iteratively. Note that the maximum input size for Base64 encoding and decoding in Oracle is 4000 bytes. ![]() The result is then printed using DBMS_OUTPUT.PUT_LINE.Īdjust the input values and output variables according to your requirements. The decoded result is stored in the v_output variable after converting it to a VARCHAR2 data type using UTL_RAW.CAST_TO_VARCHAR2. In this example, the UTL_ENCODE.BASE64_DECODE function is used to decode the input string ( v_input). V_output := UTL_RAW.CAST_TO_VARCHAR2(UTL_ENCODE.BASE64_DECODE(v_input)) The encoded result is stored in the v_output variable and printed using DBMS_OUTPUT.PUT_LINE. The UTL_RAW.CAST_TO_RAW function is used to convert the input string to a RAW data type, which is then passed to the BASE64_ENCODE function. In the above example, the UTL_ENCODE.BASE64_ENCODE function is used to encode the input string ( v_input). V_output := UTL_ENCODE.BASE64_ENCODE(UTL_RAW.CAST_TO_RAW(v_input)) Here’s an example of how to encode and decode data using Base64 in Oracle: On web.oid_web_activity_fct = o.In Oracle, you can perform Base64 encoding and decoding using the UTL_ENCODE package. On WEB.OID_WEB_ACTIVITY_FCT = C.OID_SILVERPOP_CLICK SUM(case when WEB.EVENT_TYPE in(5,6,7,8)then WEB.ACTIVITY_COUNT END) +o.count(*) as Totalįrom GMMI_AIR.WEB_ACTIVITY_FCT WEB join GMMI_AIR.SILVERPOP_CLICK C Sum(case when c.when_clicked is not null then c.count(*))as clickcount, SUM(case when o.WHEN_OPENED is not null then o.COUNT(*))as OPENCOUNT, -In this table they don’t have seprate field named ’Actitvity_count ![]() SUM(DECODE(WEB.EVENT_TYPE,7,WEB.ACTIVITY_COUNT,0)) as DISCUSSIONVIEW, SUM(DECODE(WEB.EVENT_TYPE,6,WEB.ACTIVITY_COUNT,0)) AS DISCUSSIONSTART , SUM(DECODE(WEB.EVENT_TYPE,5,WEB.ACTIVITY_COUNT,0)) AS DISCUSSIONCOMMENT , I also like case statements as I have been using Sql server all the time, but in this job they use ORACLE and part of the query was already written, I had to add few more columns where I tried something like this! I am really confused as I can do sum of one activity in decode but how do I write statement where in one decode statement it's adding up more than one activity?Īnd also want to ask that if some event is coming from other table can I still use the joined fields from other tables in my decode statement? I am confused if I can do something like this? Most of the events are coming from one table, but in one column I have to show total of( open+view+print+register etc) and this all should come as one column as engagement _count along with other individual counts. SUM(DECODE(WEB.EVENT_TYPE,35,WEB.ACTIVITY_COUNT,0)) AS Cpn_Aprt SUM(DECODE(EVENT_TYPE,33,WEB.ACTIVITY_COUNT,0)) AS Cpnw SUM(DECODE(EVENT_TYPE,34,WEB.ACTIVITY_COUNT,0)) AS Cpn_Red , SUM(DECODE(EVENT_TYPE,5,WEB.ACTIVITY_COUNT,0)) AS DISCUSSION, SUM(DECODE(EVENT_TYPE,2,WEB.ACTIVITY_COUNT,0)) AS BLOG I am trying to provide counts of different activities from one table, however few counts will come from other table and in the same query I also have to provide sum of 5 activities in one column. ![]()
