Query input data from HTML to flask mysql - mysql

Question

I am both new to flask and posting here.
I am trying to query a MySQL database with a variable input from HTML to Flask.
If I fix the query from the python code, it works. However, trying to query my database using the input variable doesn't give any result.
Here is my HTML code for the input variable :
<div class="search">
<form action="{{ url_for('search') }}" method="POST">
<input type=text name="search"></br>
<div class="actions"><input type=submit value="Search"></div>
</form>
</div>
Here is the python code for the search query:
#app.route('/search', methods=["POST" , "GET"])
def search() :
if request.method == "POST" :
search = request.form["search"]
cursor=mysql.connection.cursor(MySQLdb.cursors.DictCursor)
cursor.execute( '''SELECT * FROM sites WHERE SITE_CODE=(%s)''', (search,))
data=cursor.fetchall()
return render_template("search.html", data=data , search=search )
else :
return render_template("search.html")
here is the jinja2 code for the output :
<table>
<td>Site Code</td>
<td>OM VLAN id</td>
<td>IuB VLAN id</td>
<td>Abis VLAN id</td>
<td>S1X2 VLAN id</td>
</tr>
{% for sites in data %}
<tr>
<td>{{sites.SITE_CODE}}</td>
<td>{{sites.OM_VLAN_id}}</td>
<td>{{sites.IuB_VLAN_id}}</td>
<td>{{sites.Abis_VLAN_id}}</td>
<td>{{sites.S1X2_VLAN_id}}</td>
</tr>
{% endfor %}
</table>
I have a fully ready to use database(I do not have to change anything in it, I just need to query searched data from it) note that everything is working fine when I try to show all the data from the table :
#app.route("/")
#app.route('/IP_PLAN',methods=['GET','POST'])
def IP_PLAN():
cursor=mysql.connection.cursor(MySQLdb.cursors.DictCursor)
cursor.execute("SELECT * FROM sites")
data=cursor.fetchall()
return render_template("IP_PLAN.html",data=data)
UPDATE:
everything actually works, I just need to type the exact name of the "SITE_CODE". is there any way to get a result without doing it? I want to get as an output all the sites that contain an A in their SITE_CODE for example.
Thanks
UPDATE 2:
I finally achieved what I wanted to do, I just had to change the cursor.execute command :
cursor.execute( 'SELECT * FROM sites WHERE SITE_CODE LIKE %s', ['%' + search + '%'])
