Oracle - using bind variable in LIKE clause of dynamic cursor

由 老子叫甜甜 提交于 2020-01-21 04:57:05
问题 I am using dynamic cursor for fetching data. Query that is being executed looks similar to: query := 'SELECT column1, column2 FROM my_table WHERE column1 LIKE ''%:bv1%'''; And the cursor itself is executed like this: OPEN my_cursor FOR query USING my_var1; I also tried to check the query and print it: ... WHERE column1 LIKE '%:bv1%' ... so apostrophes are escaped, but the cursor fetches no data. Is it even possible to use bind variables in LIKE clause and if yes, what did I do wrong? 回答1:

Oracle optional bind variables

问题 I have a query to select users from a table, given user id. This parameter is optional. This is the query: SELECT * FROM USERS WHERE (USER_ID = :USER_ID OR :USER_ID IS NULL) ORDER BY USER_ID; Now I execute the query finding one user, so :USER_ID takes the valor 1 : SELECT * FROM USERS WHERE (USER_ID = 1 OR 1 IS NULL) ORDER BY USER_ID; This query takes 5 seconds. And then, I add to the previous query OR :USER_ID IS NULL many times. This example takes much more time than the first: SELECT *

jooq issue with limit and offset

由 眉间皱痕 提交于 2019-12-12 13:39:11
问题 I have integrated jooq with spring and for all types of querying to the database (MySQL), I am using JDBC Template of spring. jooq library is used here to generate the sql query to pass to jdbc template.

I am generating query as follows: create.select(Factory.field("table_name")) .from("tables t") .where("t.table_schema LIKE '" + schemaName + "'") .limit(10) .offset(2) .getSQL(); I am getting error as follows

问题 This is a stupid problem, but I can't seem to get around it. I have a query that's causing trouble in an OCI program, so I want to run it manually in SQL*Plus to check if there is any difference there. This is the query: select e.label as doc_name, e.url, i.item_id, 'multi' as form_type from cr_items i, cr_extlinks e where i.parent_id = :comment_id and e.extlink_id = i.item_id UNION select null as doc_name, utl_raw.cast_to_varchar2(DBMS_LOB.SUBSTR(r.content, 2000, 1)) as url, r.item_id,

问题 After Googling a lot and not finding what I'm looking for I decided to ask this question. I'm using binding variables as demonstrated in this awesome article from 2005 titled The Values That Bind by Mark A. Williams, like this: OracleParameter p_APP_NAME = new OracleParameter("p_APP_NAME", OracleDbType.NVarchar2, ParameterDirection.Input); p_APP_NAME.Size = 50; p_APP_NAME.Value = log.Application.Name; cmd.Parameters.Add(p_APP_NAME); I successfully enabled ODP.NET debug tracing but one key
