Check if MySQL table exists or not [duplicate]

Answer 1

$result = mysql_query("SHOW TABLES FROM $dbname");

while($row = mysql_fetch_row($result)) 
{
    $arr[] = $row[0];
}

if(in_array($table,$arr))
{
  echo 'Table exists';
}

Answer 2

Updated mysqli version:

if ($result = $mysqli->query("SHOW TABLES LIKE '".$table."'")) {
    if($result->num_rows == 1) {
        echo "Table exists";
    }
}
else {
    echo "Table does not exist";
}

Original mysql version:

if(mysql_num_rows(mysql_query("SHOW TABLES LIKE '".$table."'"))==1) 
    echo "Table exists";
else echo "Table does not exist";

Referenced from the PHP docs.

Answer 3

You can try this

$query = mysql_query("SELECT * FROM $this_table") or die (mysql_error());

or this

$query = mysql_query("SELECT * FROM $this_table") or die ("Table does not exists!");

or this

$query = mysql_query("SELECT * FROM $this_table");

if(!$query)
   echo "The ".$this_table." does not exists";

Hope it helps!

Answer 4

$query = mysqli_query('SELECT TABLE_NAME FROM information_schema.TABLES WHERE TABLE_NAME IN ("table1","table2","table3") AND TABLE_SCHEMA="yourschema"');
$tablesExists = array();
while( null!==($row=mysqli_fetch_row($query)) ){
    $tablesExists[] = $row[0];
}

Answer 5

Use this query and then check the results.

$query = 'show tables like "test1"';

Answer 6

MySQL way:

SHOW TABLES LIKE 'pattern';

There's also a deprecated PHP function for listing all db tables, take a look at http://php.net/manual/en/function.mysql-list-tables.php

Checkout that link, there are plenty of useful insight on the comments over there.
