PreparedStatement pstmt con. To this method pass the insert query (with place holders) as a parameter. We will start with the simple SQL select query used to collect the names and ids of the students from the table. Create a PreparedStatement object using the prepareStatement () method of the Connection interface. You can see different mysal connection strings used in different scripts here. We are not discussing the connection to mysql part here and we assume connection is open for us.

The small PHP code we will discuss you can copy and use directly from here.

For our demo here we will use the student table and you can download / copy the SQL dump file to create your table with student data. In second stage we will add restriction by using a period button to the list box. Query editor cannot connect to a replica database with ApplicationIntentReadOnly. To connect to the master database, explore one or more clients in Next steps.
CONNECTED DATABASE WORKBENCH SPINNING ON QUERY HOW TO
In the first stage we will learn how to get the data from MySQL table and then populate the list box. Query editor doesnt support connecting to the master database. This example you can extend to any other condition like displaying state list with population more than some value. Then we will add a restriction and collect only the records of the boys from the table. || ' WHERE ' || ALL_TAB_COLUMNS.COLUMN_NAME || ' LIKE ''%hello%''' || ' 'ĪLL_TAB_COLUMNS.Populating drop down list box as options by using Data from MySQL table.įor example we are populating the list box with student names at the first stage. || 'FROM ' || ALL_TAB_COLUMNS.OWNER ||'.'||ALL_TAB_COLUMNS.TABLE_NAME 'SELECT ' || ALL_TAB_COLUMNS.COLUMN_NAME || ' AS RESULT_FOUND, ' The result will be some or many sql scripts (based on your tables column types) and running them will result your answerĪlso performance and time consumption will be another matters. %hello% is search keyword replace it with any string. 'VARCHAR2','NVARCHAR2','NCHAR','CHAR' refers to string column types in Oracle, you have to replace them with equvalents type names of MySql I focus on a simple template solution for your question implemented in plsql for Oracle database, I hope customizing it on MySql, being simple throw googleing.Īll you need is to investigate information schema on MySql and replaceing some table name and columns.ĪLL_TAB_COLUMNS is an information schema table containing All Table Columns SET = CONCAT("SELECT * FROM (", ") `results` WHERE `occurrences` > 0") Select Only return results with at least one occurrence WHERE `table_schema` = `column_type` REGEXP `results`
'WHERE `', `column_name`, '` ', NULL, NULL) `query` instead of selecting the query over and over again as it's built
Use `DISTINCT IF(QUERYBUILDING, NULL, NULL)` Build query for each table and merge with previous queries with UNION
You can return all columns from all tables that match any values you're looking for all at once by building off of RolandoMySQLDBA's answer and using PREPARE and EXECUTE to run the query. SHOULD: add the two back ticks shown below for tables which have a space in the name. The output tells you the Database, Table, and Column the data appears in.ĮDIT: CONCAT('SELECT ',QUOTE(db),',',QUOTE(tb),',',QUOTE(col),',COUNT(1) FieldHasItįROM ',db,'.',tb,' WHERE \`',col,'\`=''',SearchString,''' ') SQL="$ -gt 0 ] then grep "1$" < MegaSearchResults.txt fi Then, execute that Giant SQL script: SQL="SELECT CONCAT('SELECT ',QUOTE(db),',',QUOTE(tb),','," (column_type LIKE 'char(%' OR column_type LIKE 'varchar(%' OR column_type LIKE '%text')Ĭreate a Giant SQL text file with it. SELECT table_schema db,table_name tb,column_name col FROM information_lumns
Please look over my old link and use its paradigm to do a search.Īs an example, this will create a separate SELECT for each text column in every table SELECTĬONCAT('SELECT ',QUOTE(db),',',QUOTE(tb),',',QUOTE(col),',COUNT(1) FieldHasItįROM ',db,'.',tb,' WHERE \`',col,'\`=''',SearchString,''' ') SearchSQL It uses the table information_lumns to pick up every CHAR, VARCHAR, and TEXT field and perform a textual REPLACE. Query to find and replace text in all tables and fields of a mysql db
