vb.net - search for a word in entire table - MySQL -

-

Currently using the following code to search for a word in the entire table, 

  String = "sample" as a slow search string as mysql = "SELECT * FROM myTable" & amp; _ "Where '%' as the call 1 & amp; Search & amp; "% '" & Amp; _ "Or '%' like call 2 & amp; Search & amp; "% '" & Amp; Like "_" or 3 as'% '& amp; Search & amp; "%'" & Amp; _ "or call 4 & quot; & quot; & amp;"% & quot; "

but increases the number of columns but if the query becomes more difficult, then anyone can suggest some alternative methods to do this.

Use a loop to make your string a program In this example, you only need to add your column to the array. 

  forms of retarded form In the form of the string = = "sample" = dimension (string) = {"col1", "col2", "col3", "col4"} as blurted boolean = true dull mysql string = "select * from myTable WHERE "Arrays in the string for each string if b mysql = mysql & str +" such as '% "& amp; Search and"%' "Other Mysql = mysql & amp;" or "& Str & Amp; "Preferences '%" & Search & amp; "%'" End if B = False Forwarded Debug. Published (mysql)

Output >>

< Pre> SELECT * myTable where '% sample%' like call 1 or '% sample' like 'call 2' or '3% Sample% 'or 3 like'% sample ''

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
